My 6600 GT came today . If works wonders in games, but when I ran 3DMark 03, it had severe artifacting during 2 different tests. I downloaded the latest drivers from nvidia website, but I still get artifacts. Has anyone else had this problem or can help me out. It is the AGP version. Could it be a heat issue? I am planning on getting a slot fan to help, but I don't think it should do this at stock speeds. Haven't had much time to test it yet.
