New PC build [1000-1300 EURO]

heredith

Hi I am looking to get a new PC. The last time I built a PC was about 2004 so it's been a while. To be honest I am tempted to just buy a Dell to not bother going through the hassle, but from reading up about it on this site, you guys seem to be suggesting all the parts... My. biggest concern is that the components won't be compatible with each other.

Hi first time builder here. Looking for any advice you can give. Thanks!

1. What is your budget? [€1000-€1300] if this needs to be broken a little or even a bit more for something that really makes all the difference then I would consider that.

2. What will be the main purpose of the computer? [Gaming//Internet/Media hub,word processing etc] (Starcraft 2, COD, BF3, Crysis and CNC Generals 2 when that comes out!

3. Do you need a copy of Windows? [Yes] what's better Windows 7 or Windows 8?

4. Can you use any parts from an old computer? No

5. Do you need a monitor? Yes I was thinking of 1080p res being enough, unless people think otherwise... Was looking at the dell one for about 200 euro

5b. If no, what resolution is your current monitor and do you plan to upgrade in the near future? Actually, might look at getting a second monitor too, so need to incorporate a second port for the monitor, though if this adds a lot of cost let me know, and maybe I won't.

6. Do you need any of these peripherals? Keyboard/Mouse - is there anything else worth getting?

7. Are you willing to try overclocking? Not really... Again if its easy to do then so be it, but its not my thing anymore...

8. How can you pay? Bank Transfer/Laser and credit card...

9. When are you purchasing? [Probably in the next month or so]

Also big important factors for me if possible...

Quiet. A really quiet PC would be really good. This thing is in the living room area of the house and a big loud or even moderately noisy PC is out of the question.

Smaller form factor if possible and not some garish lights everywhere PC... Something simple and understated looks wise would be good. Maybe plain brushed aluminium or black etc...

I would like an SSD if possible in the budget... I like the sound of a quick boot up time!

Ok that's all. Sound a bit spoilt I'd say there... But just trying to get I. Everything that I am looking for.

Thanks... Looking forward to the feedback.

An overclockable processor and motherboard - OCing is extremely easy now-a-days, no excuse not to really
A very good, and quiet, CPU cooler
A very well regarded and small case - It's actually what I'll be switching to as soon as I can
A solid state drive - Will make the whole machine very snappy indeed, and makes no noise
A high efficiency power supply to keep noise down, and generally, why not?
A good graphics card with a quiet after market cooler
Much better fans - Extremely quiet for the air they push, meant as replacements for the H100i and stock case fans

Hope that helps.

heredith

Oh I meant to say the monitor should be about 23"

Serephucus

It is a 23" monitor.

heredith

Hi Serephucas... Didn't see your message there thanks for the quick reply... Will read through your options there...

Just wondering is that nvidia card much different to the non TI version in the Alienware x51 computer... Which I don't want to buy... By the way... But just catching up on my info all things computers lately...

Serephucus

http://www.techpowerup.com/reviews/Gigabyte/GTX_660_OC/27.html

If you scroll down to the 1920x1200 section, you'll see the 660 (94%) then the 660 Ti (111%), so it's a good bit slower.

BloodBath

That's a great build. Cant' say I'd change much.

Just that is the German version of windows. Windows 8 has some nice features like ultra fast boot which gets boot times down to about 5 seconds from powering on compared to 10-12 seconds with W7. (with high speed ssd's)

Not really a big deal but still nice. The ui is the main problem and a lot of people don't like it but performance and feature wise it is the better os.

For €15 more this ssd is far superior and has a longer warranty.

http://lb.hardwareversand.de/Solid-State-Disk/67801/Samsung+SSD+840+Pro+128GB+SATA+6Gb+s.article

Since you're not getting a Hdd you might need a bigger ssd. The 256gb version of the same ssd which also happens to be faster and includes a free copy of Assassins creed 3.

http://lb.hardwareversand.de/Solid-State-Disk/67799/Samsung+SSD+840+Pro+256GB+SATA+6Gb+s.article

Serephucus

Yup, I have to say I'm actually quite jealous of that build. :P

Would have thrown it in (there actually was a 256GB SSD in there originally) but given his budget, and that the build doesn't include a keyboard or mouse, I left it at 128.

heredith

Thanks for all the advice! That's great...ok so would it be worth adding another 8 GB of ram to that to give 16GB? Looks like a reasonable price for another 8GB ram.

I was already looking at a 256 gb ssd ...thanks for that Samsung suggestion ... Will take that on board...just out of curiousity ... Why is the Samsung ssd hdd better than the Crucial?

I was thinking would it be worth going for an extra 1 or 2TB second hard disk drive for space...would it fit... Or at least if I knew it would fit I can get it in the future...

I know I'm going over my budget here but just exploring options... Hope that's ok.

heredith

Also actually, where would I get an English version of windows 7 or windows 8?

MiskyBoyy

I'm not an expert but apparently 8gb ram is enough for anything and is the optimum amount required for gaming.

Also, as far as I can see, that case has plenty of free drive bays so adding HDD's in the future shouldn't be a problem.

For English Windows, you can also get it from that same site:

http://lb.hardwareversand.de/OEM-Software/67054/MS+Windows+8+64bit+%28SB-Version%29+Englisch.article
Actually... Just found it after a little rooting around on that German site.

Should I get the pro version or the normal version... I presume I should go for the 64 bit or am I wrong?

Also just with regards to the last sentence on that list of components...

"Much better fans - Extremely quiet for the air they push, meant as replacements for the H100i and stock case fans"

Does that mean I get that scythe fans AND the h100i or I get the fans OR the h100i?

Thanks again for all your help!

MiskyBoyy

In regards to your choice of Windows 8 or Windows 8 Pro:

"Windows 8 Pro is comparable to Windows 7 Professional and Ultimate[4][5] and is targeted towards enthusiasts and business users; it includes all the features of Windows 8. Additional features include the ability to receive Remote Desktop connections, the ability to participate in a Windows Server domain, Encrypting File System, Hyper-V, and Virtual Hard Disk Booting, Group Policy as well as BitLocker and BitLocker To Go."

Unless you plan on using any of these features then save yourself the money and get the normal edition.

Yes, 64 bit.



Also, if you prefer the black version of that same case, here it is:
http://lb.hardwareversand.de/Mini/60296/BitFenix+Prodigy+Mini-ITX+Geh%C3%A4use+-+schwarz%2C+ohne+Netzteil.article

heredith

Thanks.

BloodBath

Does that mean I get that scythe fans AND the h100i or I get the fans OR the h100i?

I wouldn't use those fans on the h100i. They have virtually no static pressure which is important for pushing air through radiators and would make that h100i about as useful as the stock cooler only quieter.

I was already looking at a 256 gb ssd ...thanks for that Samsung suggestion ... Will take that on board...just out of curiousity ... Why is the Samsung ssd hdd better than the Crucial?

It has slightly faster reads, much faster writes and much faster random reads/writes. It's pretty much near the limits of sata 3. Drives won't get much better than this on sata 3.

Should I get the pro version or the normal version... I presume I should go for the 64 bit or am I wrong?

Noramal 64 bit version.

The black version of the case has a mesh front where as the white's is solid. The white should have better sound dampening where as the black should have better airflow.

This is a build I put together recently:

Coolermaster HAF 922 Mid Tower Chassis

Asus SABERTOOTH Z77

Intel i7-3770K

XFX Radeon HD 7970 DD 3GB

Corsair Vengeance 8GB RAM

Coolermaster Hyper 212 EVO CPU Cooler

Seagate Barracuda 1TB 7200RPM

Corsair HX750 Professional Series

Microsoft Windows 7 Home Premium 64-bit

Samsung 24" LED Monitor(1920 x 1080 Full HD, 2ms, HDMI/VGA)

It's a little bit over your budget, about 1500 Euro or so via Amazon.co.uk but it is an absolute beast and future proof for a fair while to come.
Sadly I used a Sabertooth P67 I got last year, and the bloody thing is bust, have to RMA it

Ok. So I'm a little confused about what I should do with regards to the fans and h100i cooler?

Do I need the fans suggested or what am I to do?

Also lets say then that I want to spend another 60 or 70 quid on a graphics card what would you suggest?

Thanks for this suggestion, but it looks a little on the big and loud side for me... Again... Thanks though.

Serephucus

If you go with the build I suggested (as regards fans) you'll get the H100i, and extra fans. The idea is that you take the H100i, throw away the stock fans, and use the extra ones in place of the stock ones.

You could add an extra 8GB of RAM if you wanted, but it's not really necessary. It's something very easily added in the future if you decide you need it, but 8GB is more than enough for gaming and anything else you might be doing with it for the moment (next couple of years)

The case does have space for mechanical drives. By default, it comes with space for five mechanical drives, and five SSDs. To get the graphics card to fit though you'll have to remove one of the drive cages, so that brings you down to two mechanical and five SSDs (still plenty). If you were to spend a bit of extra money on the GPU, I'd look at the GTX 670. The Gigabyte version that I chose is ideal because that's the type of cooler this case is designed to work with.

BloodBath

If you aren't going to overclock you could save €150-200 on that build and still keep it quiet.

Small form factor and silence don't exactly go hand in hand with overclocking but sereph's suggested part's are probably the best way to do it.

I'd also take a 7950 over a 660ti and 670gtx. It performs on par with the 670gtx and costs less.

Serephucus

I'd have to disagree there. It gets higher framerates, yes, but recent reviews have shown that AMD still haven't nailed down their frame latency problems. I'd take more consistent framerates over higher averages personally.

http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/59785-nvidia-geforce-gtx-titan-6gb-performance-review-15.html

Not the best example, but it's the newest I could find, and probably one of the few using AMD's new drivers that supposedly patch the problem. Bearing in mind that Titan stutters quite a bit more than the 660 Ti/670/680.

BloodBath

Those benchmarks show varying frame latency across all cards. The 7970 performs better than the gtx 690 and titan in some and worse in others. It's all driver related and amd (and I'm sure Nvidia) are working on improving it in more and more games.

There is some chronic spiking in some.

13.2 driver's are still in beta though.

Serephucus

The 690 is a dual GPU card; I'd be worried if it didn't have latency problems compared to a single GPU. The titan is brand new and has more latency issues than the GK104 core cards.

You're right - It is driver related, and I'm sure both camps are working on solutions, it's just my personal preference to go with NVIDIA as they typically have less issues. I'd be especially inclined to go with NVIDIA given that the 600 series cards might very well see GPU Boost 2.0 functionality enabled in the near future, which would be a huge boost (no pun intended) in customisation, and performance.

BloodBath

Here's another recent article with more relevant 7970 vs 680gtx comparrisons. It's a mixed bag across games when it comes to frame latency. The amd cards are definitely behind though but it's really only an issue in a couple of titles.

http://www.tomshardware.com/reviews/geforce-gtx-titan-performance-review,3442-3.html

Serephucus

I'm not sure what you mean by mixed bag. In that link, of the six games they tested, the 7970 was worse than the 680 (mostly by a huge margin) in five. The exception being Borderlands 2.

BloodBath

I'm not sure what figures you are reading. If you think you can notice the difference between 4 and 6 ms then you have great eyes. Not even taking the triple monitor setups into the equation here.

They are so close in 4 that it would not be noticeable except for FC3 and WOW where the 7970 seems to be having issues.

It's ahead in borderlands 2 and bf3.

Serephucus

I'm looking at the consecutive frame latency charts. You're looking at framerates, by the sounds of things.

And it is something I notice. This is someone who's legally blind, my eyesight is that bad, an I notice that Borderlands 2 feels a bit... choppy, skittish, almost, to me on my 670, even though I'm getting a good framerate according to Afterburner. If I didn't know about frame latency, I couldn't nail it down to that, but I would be able to tell you that the game doesn't feel like it's running very well.

BloodBath

According to those charts at 1080p a 670gtx should be having no frame latency issues. Even at 1440p those latency figures are low enough to be a smooth experience unless it's spiking which we can't see in those charts. Unless bumping up the physx also bumps up the latency.

Serephucus

Agreed. In Borderlands 2 they're mostly even, I was just saying that it's the one example where the 670 fairs noticabely worse than the 7970. If you look at Far Cry 3 as an example though, the 7970 does a lot worse here. That's more representative of what the other titles show as well.

BloodBath

Not really, FC is the exception and the latency issue here is pretty awful and definitely noticeable. I really hope they fix this in the final 13.2 release.

heredith

Hi Bloodbath & Serephucus.

Ok so... re-read the thread. And just did some reading myself in places such as tomshardware etc...

I have a few questions:

1. The black case and the white case? You say the white one is better for sound reduction and the black one is better for airflow? Do you think if I went for the black one it would be a problem?

2. If I hold off on the 16GB and get only the 8GB Ram, I suppose I could get more if I need to in the future. Does this

3. Quote from Bloodbath about the fans:

BloodBath wrote: »

I wouldn't use those fans on the h100i. They have virtually no static pressure which is important for pushing air through radiators and would make that h100i about as useful as the stock cooler only quieter

This goes against the statement by Serephucus:

So what should I do - I think if I was to go ahead with this build I am pretty much persuaded by Serephucus's first post on this thread, but after Bloodbath said that I just wanted to check?

4. Ok. Lots of talk here about GTX660ti, GTX670 and the ATI HD 7950, and the 7970... Did a bit of reading and it all seems pretty close to me in some areas. The way I look at it, the monitor I am buying is the one attached so the only performance I will be seeing will be on 1080p monitor... as I said if the GTX660ti is EUR250 (http://lb.hardwareversand.de/articledetail.jsp?aid=65488&agid=1156). I am willing to go to maybe 350 if its was worth it for a better card... however reading that you (Serephucus) said that you specifically picked the Gigabyte GTX660ti for the slection of my computer to do with the cooler working with the case... can you clarify that for me?

Serephucus wrote: »

I am really sorry for all of the questions, and I know they may all seem like little nuanced things, but for me this is the only PC i'll be buying for the next 4 years at least and I just want to make sure that I understand what I am getting.

Again... really really really appreciate the help. There is no way I would be doing this if it wasnt for the help on this site... all the other blogs and reviews etc etc, get so confusing!

heredith

oops.. you can ignore question 2... I answered that one myself... the motherboard can only take 16GB so I may as well just get it now and that'll be the end of it.

BloodBath

The black version should still be fine. My only issue was spending €125 on a cooler that you aren't really taking advantage of. Sure it will be silent but you could throw a cheap ass 212 evo in there, turn down the fan speed a little, and it would still be silent or close enough to it. Anything below 30db is virtually silent in a living room. This is assuming it would fit.

The H100 is a great cooler but I'm not sure how great it will be with those fans on it. Silent for sure but the graphics card is going to be at least 30db anyway so it really doesn't need to be that quiet.

Go for a 660ti or a 7950. It's not worth the extra for the higher end cards.

Serephucus

You're telling me that if you take a Hyper 212 EVO with one 600RPM fan on it, that it will cool as well as a H100i with two 600RPM fans? Not bloody likely. Where watercoolers excel is low RPM.

Heredith:

Black/white is really up to you. When I get a Prodigy I'll be getting a white one for noise reasons, but my build will be quiet different to yours sound wise. I'd still lean towards the white one. If there's not enough airflow, there are a couple of ways you can increase it. I also think the white looks better, but again, that's personal preference.

Our points (Mine and BloodBath's) with regard to the H100i were the same: It sort of sucks with stock fans (the fans that come in the box with it) which is why I included much better fans. If you use the much better fans, it'll be an excellent cooler.

Yup, the board only takes 16GB. If you want you can buy it now, but it doesn't make much different. It's a ten second job to open the case and pop in another RAM stick if you decide you need more down the line.

The reason I picked that Gigabyte card is that it's got two big fans on it, vs. the standard one small fan. The two bigger fans will be quieter, and they work well with the case considering one side of it is full of ventilation holes. This way you get a bunch of cold air being pulled in, and getting blown straight over the card, which should keep it very cool.

As regards the 660 Ti/670 (Gigabyte does the same version of both, so no worries there) or a 7950, I'll leave that one to you. I think I've derailed your thread enough as-is. :P

I hope that's everything. Feel free to fire more questions at us.

heredith

Thanks very much for the comprehensive answers..

need to go and digest this and will get back to you if I have any more questions, but I think you two answered most of my questions are answered...

To be honest, I do like the white case myself... looked at it again...think it would look good...

as for the graphics card?...

http://lb.hardwareversand.de/2048MB/59042/Gigabyte+GeForce+GTX+670+OC%2C+2GB+GDDR5%2C+2x+DVI%2C+HDMI%2C+DisplayPort.article

would this one be compatible? It has three fans instead of the two on the 660ti, but I suppose thats a good thing... and I presume it would still fit?

Serephucus

Yup, should be fine.

Make sure to post pictures when you get it built. I'm actually quite jealous.

BloodBath

You're telling me that if you take a Hyper 212 EVO with one 600RPM fan on it, that it will cool as well as a H100i with two 600RPM fans? Not bloody likely. Where watercoolers excel is low RPM.

No I'm saying the 212 evo is already a very quiet cooler. 31db at the max setting.
http://lb.hardwareversand.de/Intel+AMD/59387/Cooler+Master+Hyper+212+EVO++-+Intel+AMD.article

It includes a pwm fan which is adjustable so you don't have to replace it. 31dba is already near silent. You could drop the fan speed a small bit to get it to 20gb if you wanted. You still won't hear it over the card or psu.

I'm saying that those silent scyte fans are virtually useless on a radiator as they have very low cfm and almost no static pressure.

heredith

I will do... just have to pursuade the girlfriend now to help me pay for it... that could be a bit of a challenge!

I reckon it could be a couple of weeks before I get the money together.

Is it awkward paying hardwareversande? - is there a whole other thread about that, that you know of?

BloodBath

No it's very easy with online banking.

Good luck. Kinda jealous myself.

Right, a few problems here:

1) You take the specs as being true, odds are they're not.
2) You've obviously never used GTs. They're absolutely fantastic fans, and by far the more recommended for watercooling radiators. I've used a bunch of different fans - Noctuas, Zalmans, Akasas, you name it - GTs are far and above the best I've used, both in terms of noise and performance.
3) I think you would. I can hear my server's 120mm fan at 5V over the other two case fans and 80+ Gold PSU.

heredith

When you are talking about the GT fans and replacing the stock fans - are you only talking about the ones around the case?

I mean I am not replacing the Corsair one that comes with the cooler unit?

Just want to get that clear... I presume that all of the fans other than the ones in the case are ok?

Serephucus

No, I included four, so you'd replace the two with the Corsair cooler, and the two that came with the case.

Believe me, it'll make a big difference.

heredith

Its all coming a little clearer now... ok. ok... I just looked over the list... I suppose I better get a DVD player/burner too... any particular brand that are good?

heredith

And will I just leave the fans on the graphics cards as they are?

Serephucus

You'll need something like this:

http://lb.hardwareversand.de/USB/56465/Asus+SDRW-08D2S-U+Lite+Schwarz+Slim+DVD+Brenner.article

Because using the H100 means you loose the optical bay. No great loss really. I don't have one in my build at all any more.

Edit: Yeah, the graphics card stays as-is.

http://lb.hardwareversand.de/2400+Low+Voltage/72730/8GB-Kit+Corsair+Vengeance+schwarz+PC3-19200U+CL10-12-12-31.article

why would someone get this ram over the ram you selected.. I can see that the bus speed is faster... but does that make any kind of a difference?

yeh your right I suppose... I could just leave it in a drawer until I need it...

I suppose I was thinking i definitely need it to install Windows onto it...

BloodBath

Well it goes against anything I learned about water cooling. I think those fans have something like 0.015 static pressure. You want fans with static pressures above 1.0 to push air through radiator fins effectively. That combined with the really low cfm means there's almost no air passing through the fins.

That dbm rating for the 212 evo is pretty accurate. It all depends at what distance you take the reading but I haven't seen any tests showing it above 35db at full speed.

I also own one at it is definitely the most quiet component in my pc.

Serephucus

That's the only time I used mine. It's been sitting in a box for three months ever since.

As regards RAM, no reason really. It looks pretty, that's about it. It's a 2x4GB kit though, so you'd be limited to 8GB max, just to mention.

Edit: Fans, static pressure is dependent on speed. You can have fans with 2.5mm H20, but they'll probably spin at 2000RPM. A lot of radiators now-a-days are designed for low speed fans, meaning they have a low fin density. In that case, you don't need a huge amount of pressure at all. In fact, the lower a fan spins, the higher its relative pressure. Think of it like torque in a car engine.

heredith

There is some serious amount learning going on here for me!

Thanks for all the input...

As regards the RAM - I am happy out with the RAM you suggested... I was just trying to understand why there are things like that one with the big black radiator and they cost extra...

Serephucus

Ah, sorry, I forgot exactly what RAM it was I specced you, as it was from another build.

The RAM you linked is much faster. It's 2400MHz vs. the (I think) 1333MHz stuff I linked you. It makes very little difference though. Where RAM speed really comes into play is heavy benchmarking and the like, games don't see a whole lot of benefit. That said, RAM a little faster than that couldn't hurt.
