I don't know.. I have the latest Catalyst drivers for my 9200se 128 meg card, and I score 125-130 on pcpitstop every time. You must have a driver issue.. the card isn't top of the line, but it has yet to let me down. Your computer is alot better than mine in other areas, so there should be no reason the Vid card is sooo slow. Has to be a conflict, or driver issue.
