This is NVIDIA's ForceWare build 66.97 for Windows 2000/XP. This driver set has been WHQL certified for GeForce series 6 graphics cards, unfortionately the rest are actually not supported. If you card is not supported I would like to suggest you use the included modified .inf file (read txt file for installation instructions), in that case you will loose the WHQL stamp though (that's no big deal).
These drivers have been pest and virus checked them and they turn out quite alright as they originate from NVIDIA's servers. Should you give them a try then let us know in our discussion forums what you think about them ! Use them at your own risk. We recompressed the file down towards 14 Mb, that's including setup.exe and all international language files.
