2560x1600 - UberSampling Disabled

At the extreme resolution of 2560x1600, you'll need a dual-GPU configuration to hit our target of 60fps. Only the HD 6990 could manage this feat with 64fps, though the GTX 590 wasn't far behind at 57fps. The GTX 580 has been reduced to 39fps and more than half the cards fell below the 30fps threshold.
