It seems to have lots of Artifacts and not better video Quality than the ATI X800XL it replaced. I benchmarked it with FEAR and it ran smooth with good FPS.
As already stated previously in this thread by others, you need to check clock speeds while running a 3D application. As far as the artifacting, it sounds like you need to uninstall your driver, clean using DriverCleanerPro, and reinstall. That should fix the artifacting if it's not a damaged card. If you do that and it still has probs, it might be RMA time.
