tupacalypse1622, you've heard from the wrong people. As I said, a colleague of mine has that exact same card, running fine with a 9800 XT bios. Y'see, there are certain (rare) 9800 XT's with 128 MB memory.
If you could read Dutch, I've got a whole forum thread (lots of pages) of people running those 128 MB cards with an XT bios.
