graphics problem with NFS Underground 2 - 9600XT

[homestarmy]

Well I just got the 9600XT yesterday... $80 after tax and rebate woo hoo!

It will work fine at whatever resolution as long as it's not on the highest or second to highest, if that happens, everything goes screwy, and when i'm in the explore mode all i can see is my taillights and the tach and a few other things... any insight?

doesn't have that many pixel shaders? (probibly non sence)
