for - games like Dirt 2
Multi apps sure, but high resolutions tend to have a big impact on cards.
Just don't expect any anti-aliasing.
It should work pretty well at 2 lower res displays. However, gaming on 2 displays is usually a pain because the center is between 2 monitors and the bezel screws it up. FPS are impossible especially with bezel correction, your crosshair is gone and you can't aim at anything because it is behind the bezel. If you are going to go eyefinity for gaming you should really go with 3.
