2560x1600 - Gaming Performance
At the extreme single display resolution of 2560x1600 Deus Ex: Human Revolution was too much to handle for a majority of single-GPU configurations. This was made evident by the Radeon HD 6970 which rendered just 49fps, while the GeForce GTX 580 managed 46fps. We still found that both were able to deliver playable performance, though there were brief moments of lag every now and then.
Enabling Crossfire or SLI significantly improved performance as we saw the GeForce GTX 590 delivering 75fps and the Radeon HD 6990 scoring 79fps. The GeForce GTX 580 SLI cards took the victory with a whopping 94fps.
