I put in a Nvidia Fx5200, P118, 128mb dual head AGP video card in the machine hoping to squeeze out a few more horse power out of the system. Windows 7 saw it as a generic video adapter. The Windows Expirence Index was at a 1.0 for the Nvidia card, which was the same as the one built in on the motherboard. Further more, Aero would not work.
Nvidia does not make a Win7 driver, the closest they had was Vista. After much searching I found a hacked version of that driver here: http://www.laptopvideo2go.com/drivers/vista/96.85/disclaimer After applying it, and rerunning the Windows Experience Index the video scores jumped up to 2.0!
