3dmark 2001 with 4403 was 2,685. The 51.75 drivers are stable and fast on my machine who cares if nvidia turned them up for direct x 9.0. All companies Nvidia and Ati cheat a little--lets get over it and start playing and enjoying our cards!
They are lowing IQ on Dx8 in some cases as well as DX9.
BUT... Having said that.....
Everyone has the right to Enjoy the products they buy. If You are totally happy with your card thats great.
(I would caution you though that if you have any hopes of playing HL2 with full DX9 effects (Which you can do with a 9600pro) you may want to consider a trade in)
