As for S_A_V's score, it might be a matter of comparing highly optimised scores to non-optimised scores. There's a difference on all levels in hardware configuration and probably also software optimisation (even drivers are different), so it's actually quite difficult to compare.
If the score's obviously bugged, please don't submit it, but if there's a difference in GFX/CPU score I wouldn't panic straight away. There is, by the way, also a difference between XP and Vista concerning the GFX scores. On Vista you can reach higher scores.
