All of the ATI cards work without a hitch, as long as you update there drivers from
www.ati.com once you have installed the board. The ones that we use are the ATI Expert 2000, but you can go with a higher quality card or cheaper card if you want.
You must have one that has at least 8mb of Video Memory on the card, this is the most important thing. I would recommend using 16mb or greater.
