I sold off my 9800XT the other day and the other person just received it today, but is having quite a lot of problems with it. He's experiencing severe tearing in HL2, momentary freezes in the stress test, and really low FPS in HL2 and along with several other games including COD. There have been no artifacts or abnormal temperature readings (idles in the 60s). He just switched over from a 6800GT that he is selling so conflict with the nvidia drivers might be a problem. But we've tried using drivers cleaner and several versions of catalysts, but the problem still persists. We've also attempted to turn off ATI AI and turning on vsync, but both didn't do any good. He's running an alienware right now with an amd64 3700+ and 2 gigs of ram. The card have ran flawlessly in my setup listed below, and with no signs of artifacts or abnormal temperatures in his setup, I'm pretty sure that the card is not defective. If anyone can offer me some suggestions that preferably won't require a format, I'll really apprectiate it. Thanks.
