Dual R9 290's

yawhat!

Would 700 watt Be Quiet be enough for dual R9 290's. I know there pretty power hungry. Have a 4670K overclocked to 4.2 Ghz as well. I see some sites say 800 watt minimum. I would have no intention of overclocking them in crossfire.

Check out the power consumption part

Do y really need two of them? Singularly, is there any game you can't max?

Not at 1440P. Battlefield 4 with resolution scale at 200% gives 20-30 FPS maxed out. Most other games with AA give 30 FPS-40FPS with 2 times AA

Ah here is the bit I was missing.

Why do you want to use a resolution scale of 200%?

I know it makes it look very nice an all but im sure if you paired it back to even 150% you should be fine.

Also wait for mantle, could make a big difference.

Sell the 290 and grab a 780ti:)

I joke but who knows if that would even be enough for 200% resolution at 1440p!! Thats askin a lot I reckon

Not sure exactly what it is but from having a check around it seems to be some form of AA super sampling.Not loads of info on it but it seems to be a frostbite 3 feature

Its a resoure hog, but it does make the game look better imo(if thats possible at 1440p:)).
I have it set to 110%, but ive really only had a little mess with it

Its under resolution scaling in the video options of the game

It's the most expensive AA possible.

If you set it at 200% you're rendering with double resolution (4 x the pixels!!!) and then filtering down to your display resolution. So basically it's 4 times the workload to do 200% vs 100%.

Thanks lads...must check it out..

Ye I just gave it a little bump, any higher and I was getting frame drops below 60fps at ultra.

From reading around a lot of people are going with 2xMSAA, a bump in the res slider and ultra for what they consider the best image.

Do watch your vrm temps if you do bump it up, seems to hammer the memory.
I read somewhere that setting it to 200% is like rendering 4k resolution for yor gpu!!

As a side note other games have the resolution slider aswell, Arma 2 being one off the top of my head.
Bump that a bit playing dayz(mod) and the game looks awsome, or should I say more awesome:)

I tried 200%...major fail...140-150 is good for me.. Never dropped under 60 fps... To be honest didnt really notice much diff to 100%..
Mind you my eyes are gettn auld and mouldy..:(

Yeah im not noticing a major difference,but everybody is different I suppose.

If I put it over 110% the frame rate take the odd dip to about 50 so ill leave it at 110%, have nothing else left to turn up anyway!
