There might be a difference of 1-2FPS but thats about it.
It plays the same up until 1440x900, unless its in sli, then you can go higher.
Edit: ok i saw some reviews and this card is crazy, it plays certain games better at higher resolutions than lower and other cards with more memory. Im gonna get this!!!
