Working on doing some research for my Windows 2000 build and am trying to document the latest ATI/AMD and Nvidia drivers that work with Windows 2000.

I'll edit as needed.

Nvidia:
Forceware 169.28 definitely has support after looking in the .INF file.
Forceware 169.32 - maybe - added support for 8800GS
Forceware 169.38 - trying to find a working download link.

Quadro 261.19 - max supported card is the Quadro 6000 according to Nvidia

ATI/AMD
Desktop graphics - Catalyst 6.2 ?

Professional graphics - depends on the card

I know there are modified driver sets for both Nvidia and ATI/AMD cards that support much newer driver releases. I'll post links to those here as well when I get a chance.

Fell free to reply with any additional info and I'll add it to this post if I feel it is helpful.
