Hmm you should be getting a higher score, but at those settings, you kinda take the vid card out of the picture, and bring in the CPU. With the same card, clocked at 185, I get around 7500 something in 3dmark2000. Not really a good score, but the Radeon dosn't shine at 16bit.
At a 32bit setting, I pretty much get the same score, around 7300 or so.
Nagorak is right though, the Radeon dosn't really shine till you get into the higher res, at 32bit.
What kind of setup are you using?
CPU?
DRivers?
Via drivers?
DX8A?
Memory set at Cas2?
Whats your front side bus speed?
With that score, im willing to bet that either something is bad wrong, or your processor is around 500mhz or so.
Good luck! And try the 7075 drivers if you have not already done so.
