I have 680SLI and the game performance is appalling. I’m running at 1920×1080 because the Surround resolutions are simply too poor, both in terms of framerate and GUI issues.
Battlefield 3 runs on Ultra at 60fps on the same setup at Surround resolutions and is the best looking game on the market.
GW2 has great art direction but the game engine feels old and clunky.
