I just got a sapphire radeon 9800 off of newegg. I popped the card in and hooked it up into the power supply and stuff - then installed the drivers off the cd. Then I tried playing quake 3, jedi knight 2, counter-strike, and battlefield 1942. I noticed that it would glitch about once a minute or so when I was playing these games - with fuzzy lines going across the screen. Anyone have any idea what the problem might be? i tried getting new catalyst drivers and that didn't solve the problem.
