I've had a pain getting mine working. I'm running win XP pro, on an abit KT7A-RAID, with a AMD T-bird 1.2 GHz. I've got a Geforce4 MX440 SE... PCI interface... yeh, yeh, PCI graphics cards suck.. but I got it for free (My dad has an old 500 MHz prebuilt with onboard video, he has no aGP interface, so he got this card... except it didn't work for him, so now it's MINE!). Anyways, I get a crapload of ugly wierd colors flying across my screen in some games. It's like a part of the wall in GTA 3 just decides to stick out into the middle of the street. Or, in Unreal Tournament 2003, wierd colored specks just appear on the walls. I've tried a dozen different builds of Nvidia's Forceware drivers, including the newest leaked one (62.20), the newest omega drivers, the drivers that came standard on the CD (a really old forceware), windows XP default drivers, the upgraded windows XP drivers from windows update, and I even tried NVHardpage program to edit some crap with it. I think it's something to do with the opengl function. I've read that this has happened to a few other people, althout they've had the AGP interface.
