I posted a great score of 8500 for myself with a 2.5ghz AMD64 and a 7800GTX. But now with the cpu @ 2.6ghz and Prime95 stable for 16 hours and the same GTX speeds, I can only muster up 8000. What gives? Do I need a format? I've thought about formating my OS drive but I'm not sure how to do it. Should I just right click on the drive icon and go to format? I've got my win xp pro cd still but it should install properly right? I think I might format but I just wanna make sure I know what i'm doing.
