My System Specs


I used to use 570 SLI with my U2711 (2560X1440). I now have one 670 and I want to comment about the frame buffer. Very rarely do I see my vram usage over 1.3GB. When I used to run 570 SLI I saw that frame buffer nearly fill up. I too was concerned and thought that with my new 2GB 670 I would find the 1280MB of the 570 was a bottleneck. For the most part I would say no, it was not. With that in mind at 1080P I really doubt there will be any tangible benefit going to a larger frame buffer.
