When I play games the graphics are perfect etc and my ping is great and I get good aquamark scores but when I play HL2 deathmatch it seems my cpu is being bottlenecked the mouse responds late etc cant spin around good/fleuently. No artifacts so far and my setup is 3700 san diago stock and 7800gtx OCed to 490 core 1300ram in fatal1ty an8 sli mb. Any opinions? Thanks!
