Well I havent gotten a chance to play UT on it yet.....Husband is a screen hog!!
From what I see you can increase the res and it appears to me you get a slight wider field of view. UT plays real nice on it. No ghosting or freezing. Also played CSS on it with no probs.
It is mainly my husband's computer but I did try playing F.E.A.R on it and WOW!!!
