I just got a gtx 680 and love it :] however ive been having 2 problems and have some questions. First Ive been experiencing horizontal lines while playing Crysis 2 sometimes even though i have vertical sink on? Also I was playing the original Crysis for a benchmark and the graphics seem almost grainy idk how to describe it but i think it looked nicer on my gts 450 at lower settings because of this "grainyness" I'm getting at the moment with my gtx 680. Help much appreciated thanks.
