2560x1600 - High Quality
At 2560x1600 we see that it takes a Radeon HD 7950 to break the 60fps barrier, while the GeForce GTX 660 Ti came very close with 59fps. The Radeon HD 7870 also did well with 55fps and the age old GeForce GTX 580 managed 54fps.
For just over 40fps the Radeon HD 6950, 5870, 6870 or GeForce GTX 480 are required, while budget graphics cards such as the GeForce GTX 650 Ti and Radeon HD 7770 couldn't deliver at this extreme resolution.
At the top of the graph we have the Radeon HD 7970 GHz Edition with an average of 78fps, while the standard 7970 managed 75fps. The GeForce GTX 670 edged out both versions of the Radeon HD 7950, though it only beat the Boost model by a single frame per second.
