That is an ancient graphics card. Get like a 8800GT minimum, or even better a GTS250.
I would recommend using the 285.62 driver set for the drivers on the Nvidia card. Just install the driver and the Physx, but I don't even think you need the display driver.
That isn't a graphics card, its a PPU from Ageia and its the pci-e version which is uncommon. It is only fit for retro use and one can do a simple file swap to manage some support with it under current drivers but it is a step by step process. I bought one to go with my 7800gs for my athlon xp machine.
