Yeah thanks, hope you have no probs at all, the backlight bleed developed over last night which was really weird as it was completely perfect, ill have to take some piccys of the new one when it arrives.
Ive only tried CSS with my new screen and im getting about 40fps at native, which isnt as bad as expected, but the next res down was something like 1800x1200 (cant recall but it was low) and i had the gfx detail up on max and it looked ok, and ran like a charm so you should have no probs at all with your GTX. Thinking about a 1800XT now, hmmmm
