Here's a suggestion that I know will be echoed by a vast number of other members:
How about you not worry about 3dmark and use your new card to play real games like GTA3, Jedi Knight II, Morrowind, Dungeon Siege or whatever strikes your fancy? Use the card for what it was designed for - to maximize your gameplay experience at a budget price.
3dmark has little to no credibility in the eyes of most of us around here. All I've ever done with it lately is put it on an infinite loop to test for system stability and that's about all I've found it to be good for. And there are other programs that can stress a computer's subsystems that aren't 40+ megs to download.
