I would say that to run those benches they have very little in the way of background services running, probably nil unnecessary, do you halt all processes? Also they are just giving AA/AF, the IQ is probably set to high performance, vsync off and also they are running SATA drives, every little bit helps in benches. They don't tell you those little things in the review, they also neglect to tell you the driver version they used for the Nvidia cards.
Nice little app to one click kill background services is EndItAll2, google it, was freeware a while back, some sites still host the freeware version.
You might like to try the
83.90 beta Win XP 32 bit driver to see if you get any benefit, it's not a speed driver but the IQ on my ultra is noticably increased, and as a latest beta should offer better support than your current driver. (assuming you are running 32bit windows)
