3DMark 2001 and 03 are entirely different scales.
10500 is very good on 3DMark 2001 for that configuration. I wouldn't expect more than 2500 on 03 though.
On 3DMark 2001, a score of 6000 will usually indicate playability in DirectX 8 games, on 3DMark 03, a score of at least 3000 would be considered "playable" for future DX9 games.
