Just recieved my open box, AGP Sapphire X800gto. Now, when it boots, its all good, but when windows starts loading, there are numerous artifacts. Then I thought I had to RMA it. Then, I started a Linux install, and it ran fine. Maybe becasue I was upgrading from a Radeon 9550 to X800, the drivers might have conflicted with each other. Cooling is fine, because I installed an AT5. Do you have any suggestions. The card seems to work. Im reinstalling XP right now.
