welcome to the world of MMO's your gpu and your computer are fine. Graphically intensive areas of online gaming eg. Main cities have to draw each of the other people moving and jumping and other animations. This is so common and nothing to worry about. If you are struggling however overclock your gpu a tad.
Well, overclocking makes things almost worst. I manually overclocked to about 4ghz (which my mobo automatically does). I have had so many blue screens and random errors since I have overclocked.
This bugs the hell out of me. Is it because of the mother board? Should I go back to a 965? My old rig had a 955 and a 6850 and ran MUCH smoother and faster with NO errors or blue screens.... What should I upgrade or remove?
