I scored a 2765 with my thunderbird 950mhz. 768mb sdram.
ATI RAdeon 9500 PRO 128mb <---- there's the reason.
Clearly I dont run games better then all the geforce 4 owners who have p4's. The only fair way to look at it seems to be if ATI owners compare with eachother, where the scores seem to range from 2500-5000, and Nvidia owners compare only with eachother where the scores range from 500-2000. 3d mark 03 definitly doesnt portray how well the cards do in todays games though, I have to agree with Nvidia on that one...
