Ok, so I'm trying to make a decent retro PC with as many windows os's as possible and the most powerful graphics card possible. Obviously this presents and issue when running windows 2000 as nobody supports it now. I wanted to start my retro PC rig from windows 2000 til vista and use 1 card. My 750 TI has drivers for XP and Vista, bot not for 2000. My 9800 gtx has a driver for all three, but is not as powerful. Is it possible to use both cards in the same rig, but assign widows 2000 to the 9800 and xp/vista to the 750 TI?
