There are two versions of the 9800, one for G5s (Pro Special Edition 256 MB) and one for G4s (Pro 128 MB). ATI also makes the 9000 Pro 128 MB. These are the only two AGP video cards that you can buy at retail for an AGP Mac. You can find a variety of ATI and Nvidia cards on eBay as well, but be careful that you get Mac cards and not PC cards flashed with Mac firmware that may not have all the features enabled.
