You play games a little right? At which resolution and at what settings?
I always try max, but I'm not a grapics whore. My screen res. is 1920x1080. I can run a game like Crysis 1 (heavier specs than crysis 2due to directX10 I believe) onmax, except for AA.
I'm a casual gamer. For example I play and buy like 2 or 3 games a year, I'm a huge fan Mass Effect for example and I'm still able to play Mass Effect 3 at max settings.
