nVidia decided that they would not comply to the programming manual for Vantage(since it's release this guide has said cpu tests must be run on cpu or PPU, not on GPU, in order for scores to be comparable across different systems), and all drivers now feature Phys-X support for every 9-series and newer card; I do beleive that even the 8800 series can run the same test the same way now too.
I don't mean to single you out, but it's a big issue in the overclocking world where this test has been held back from global ranking @ HWBOT due to this and other issues. It's not anything you've done, but whayt nV does with thier driver.
If you install Phys-X driver, you can disable geforce accelleration for Phys-X, or you can do as Futuremark suggests, and "disable PPU" in vantage.
