dude dont push ur memory that high. those little blue lines is artifacting veryy bad for ur system. and ur gpu is better than a 7800gtx becaues even if u do get it that high ur artifacting. 7800s dont artifact at high lvls.
its 540 core, and 490 on the memory, 980 effective. whoa whoa whoa, when did 6600GTs get >500 on the core?? That is unheard of. I can only get 410 on the core for my 6800GT. A screen shot would be nice.
Just got done playing the COD 2 demo on 1024x768 with all settings on high and 4xAA and antiscoptic filtering. Damn that game's graphics are'nt THAT great, but that's because I need an LCD monitor.
