VRAM usage at higher resolutions

[Guest2]

I am deciding upon a GPU upgrade and if I should get a newer card with more VRAM (as I game at 1440p) or just go SLI.

Everyone is generally saying that I should get a newer card as it has more VRAM - 3gb / 4gb so will play much better but does anyone have any proof that more VRAM = more FPS at a higher resolution?

I found this article where a GTX 760 4GB was tested against a 2GB version

http://www.legitreviews.com/gigabyte-geforce-gtx-760-4gb-video-card-review-2gb-4gb_129062/4

We played through a couple maps on BF4 and we were able to get the memory usage up to 2997MB, so having 4GB of memory might help here and there. The bad news is that by the time you need more than 2GB of frame buffer the GPU doesn’t have the power needed to game at that resolution.

I would be interested if anyone else games at 1440p / 1600p where they can show more VRAM = more FPS

Is it possible to VRAM limit a graphics card on say a 780Ti down from 3gb to 2gb? Then bench and see results

personaly i think memory is important right now, maybe old games need a mode like GTA 4, sleeping dog HD, or skyrim HD etc, but with new consoles and next gen games resolution of textures will become higher and my guess memory usage will increase, with up coming game like, the division tom clancy, beside right now that gpu drivers works well on sli/crossfire, make it even more important to have enough memory, because if you have that you can add a 2nd hand card for extra perf, but you cant poop out extra memory even if you have enough juice to push.

I think I just died of suffocation reading that!

There's also been a few users here stating they went 2Gb 6 series SLi to 780 and noticed smoother gameplay with high AA@1440p.

I think I read a couple of those statements. Buts that all they were

I would good to see benchmark / games FPS stats. Probably the best would be something like a 670 2gb vs 670 4gb comparison (or limiting a 780 to 2gb)

Another indication I am taking the right decision by just getting another 670

just had similar results in the Valley benchmark.

single 670 - 990 (23.7fps)
SLi - 2052 (49.0fps)

Ultra settings, 8xAA, 2560x1440

Go for the second GTX 670

If you want to see any benchmarks as to what to expect let me know. I use a GTX 690 (about the same performance as GTX 670 sli) and can run some benches for you but they will be @1600p (I don't own a 1440p monitor).

Thanks

Doesnt the 690 have 4gb vram though instead of the (standard) 670 SLI having just 2gb. Sort of defeats the object - but thanks though

Great thanks for confirming. No issues playing at 1600p with 2gb Vram?

Skyrim is terrible IMO. Problem avoided!
