My 3dmark05 was at 9877 today with my 2500 quadro

I know that on a revision 1 card the memory wont clock as high as on the rev 0. But when i had my GS i flashed the clocks to 500/600 (gtx clocks)and it was fine all the time. When some people have had there memory to 800
3500 score is rather low for 3dmark05, i was getting that with my 7800go videocard. You should be getting around 7000 with a 7900gs.
Make sure in the driver settings that you have it set to performance and not quality or both. Also make sure that you dont have any processes running that are not needed.
What cpu do you have? also what drivers are you running for your 7900gs?
