I don't think that would work to be honest(if you want both to work at highest speed), would work on a X99 board with mid to top end CPU.

Your i7 6700K only has 16 PCIe lanes while you would need 32 to get the most out of both 1080. You can waste your money on a second 1080 but each 1080 will only work at x8.

Single card, negligable difference.

Two cards, from 0% to 15% depending on the game and card.

There are some arguments that nvidia's High bandwidth SLI bridge was created specifically for this x16/x8 setup.

Tbh I personally would prefer to run both at x16. The second link showed there was improvements running both by 16. He also never ran both x8 but one by 16 and one by 8.

He was also running a Titan XP in SLI too.

so what your saying is my mobo (msi z170 gaming carbon) can only run x8 on the first pcie slot if i use the second which will then also run at x8? surely theres people using 1151 with sli/crossfire setups.

so basically a skylake setup means sli is pointless?

Not just skylake, the vast majority of boards. Also crossfire has the same problem.

I think some of the very high end boards allow x16/x16 but there are very few of them and also almost cost as much as a 1080 (if memory serves).

To be fair, I'm not sure there is anything that would require two 1080s in SLI, unless maybe you were gaming at 8k or something.

Regardless, if you were running two 1080s in SLI my understanding is that you would only see a 15% drop from the expected improvement, so instead of improving your set up by 100%, a second 1080 would mean an improvement of "only" 85%.

Edit: Also thinking about it a bit more, you are far more likely to hit other bottlenecks e.g. CPU bottlenecks, a long time before you reach the potential performance of the 1080s in SLI, even with the 15% drop.

60 fps ultra 4k gaming is my aim, was going to buy a nice monitor (have an aoc 60hz 4k) but tbh the one i want isnt out yet, holding out for a ultra wide with 144hz, g sync, and a resolution between 1440-4k.

the little bit of research i did on x8 vs x16 last night tells me that theres very little performance loss, as in 1% on a single card, so i cant imagine the hit will be earth shattering

theres no way a 6700k will bottleneck 1080's surely! if thats the case il have to upgrade my cpu the next time i want a new gpu

Buy a single Titan X (Pascal).

in games that scale with sli the 1080's perform better, plus i dont have a custom liquid loop to hook a titan (which is what you should do tbh) up to

SLI and crossfire are a pain in the hoop. You don't see double scaling with SLI either, its usually around 150% of a single card. It breaks frequently, encountering fps drops, bugs and glitches that other single card setups never see. You need to purchase a Specific expensive high bandwidth bridge.

SLI at x8/x8 would be affected because the cards crosstalk a lot. So your looking at about 135% performance of a normal card. If you have the money to afford two 1080's, you have the money to buy a single Titan XP and save yourself a headache.

problem is i already have a 1080, dont really want to go through the hassle of selling the damn thing you know, plus its actually a great card. so it seems like everyone thinks sli 1080's with a 6700k is a plain terrible idea, is sli scaling really at 50% when it works? thought it had had gotten much better years back

Did a bit more reading there. It looks like a lot of sites have benchmarked 1080s in SLI using a 6700k. The GPU seems to be the bottleneck for most games at the moment and going SLI in most games will see an improvement.

Also, for most games you it looks like you should get 40-60FPS using a single 1080 for 4k at 60Hz.

If your main aim is going to be 2560x1440p @ 144Hz then I'd say a 1080 could be ok for 60 FPS. If you are ultimately going for 4k @ 144Hz though, then you are probably best just holding off until a) those monitors come out and b) for the next generation of cards.

I'm not sure that even two 1080s in SLI would get 60FPS for 4k @ 144Hz.

Icyseanfitz · 07-09-2016 10:28AM

From what I've read sli 1080's are able to hold 60fps @ ultra @ 4k if the game supports sli, other games like hitman get like a 5 fps boost or none at all due to no sli support, saw a bench of 1080's having a avg 75fps @ 4k in the witcher 3

Xenoronin · 07-09-2016 10:30AM

Monitor refresh rate doesn't stress a card. You are making it sound like having a high refresh rate will end up lowering your overall FPS, which simply isn't true.

I don't think it's a terrible idea, I just didn't think that you would get the maximum potential out of it. Techpowerup did a review with a 6700k and 1080s in SLI and it looks good. The board that they used also only has x8/x8 so it would be a good comparison for you.

Unless you are struggling to get 60FPS using ultra settings on 4k though I'm not sure if it is worth getting another 1080 (unless money isn't an issue).

If you are close to 60FPS at 4k though, you could try waiting a few months and see if a 1080TI comes out that would give you the desired performance boost to 60FPS and then think about getting two of those.

Icyseanfitz · 07-09-2016 11:21AM

Wonder will they even release the ti of the 1080

Can't spell it as gaelige Dark Horse, but £1000 is loads for a great machine

Icyseanfitz · 07-09-2016 07:08PM

if i do decide to sli, how do i figure out the spacing between my pcie 1 and 2 slots to get the correct hb bridge?

Thanks DS. Need to buy monitor, windows and stuff but can add a bit for that.

ShadowHearth · 07-09-2016 07:25PM

I think better idea just to wait for 1080ti and take it from there. Sure, if you got money to spend, then go for it.
I don't really think 6700k will be as a big issue as it's being presented here.

Revoker88 · 07-09-2016 07:45PM

CPU does come into the equation when your looking for 100fps+,current monitor the op has is 60Hz so can t see the 6700k being and issue at 60Hz @4k

Thing is I would but I really don't see nvidia rushing to release it, where will it sit? The titan is only a small bit faster than a 1080 which is already overpriced.

If they release a ti which is nearly at titan speeds for 700ish gbp they kill off the titan.

As for over 100fps, surely at 1440p/1080p a 1080 with a 6700k will go over that in a lot of games

Titan is not really a gaming gpu. Even nvidia kind of saying it's for other uses. So I bet they will release 1080ti sooner or later.
The only thing that is going against it - completely no competition in high end gpus, that was not the case last time. Yes nvidia still took the gravy spot, but Amd still was there. Why would they even bother with 1080ti.
So as you can see, just more speculations.

As for 2x1080 now. If you cam afford it comfortably, then **** it, why not. If you go resolution of 1440p widescreen, then gpu will still be a bottleneck. You lose a few fps due to sli? Well, we all know sli does not scale 100% and surely you know it, few percentage there here.

Tl:dr version: You can afford it now, then go for it. Live only once, enjoy massive ePenis.

This is weird.

980 Ti was rock-solid at +100 core / +250 VRAM overclock in Witcher 3, but in Overwatch I got hard lockups.

Had to turn off the extra OC and turn some settings down to High

You should check task manager if you can. I've found that the only times OW locked up/crashed for me was due to ShadowPlay capture service going a bit haywire. Toggling it off/on seemed to fix it (intermittently, anyway).

Not ship to parcel motel. Tried before and had my order cancelled. Really annoying because they do decent deals now and again.

What about An Post's Address Pal which is similar to Parcel Motel but use a Mainland UK address?
