That is on gamer settings though. On enthusiast settings, the gap increases to 15 fps. I am pretty sure there is some CPU bottlenecking going on as well. For example, in a more GPU intensive game, the difference is a massive 22FPS. They are using an old i7 965, when even my email@example.comGhz produces a slight bottleneck for my GPUs. The extra 512MB VRAM of the 580 helps with things like AA and high res textures as well.Not to belittle the 560Ti. It's a great card, but its no 580.
