Even in a 733 Quicksilver, this card was very good. It ran older games like Quake 3, Unreal Tournament, Alice and Wolfenstein at 50+ with graphics settings and resolution all the way up. It runs Warcraft III with settings all the way up and resolution 1280x1024 at 40+ FPS. Halo and C&C Generals run poorly only because of the processor in the Quicksilver, they would run fine in a better computer. This card is very good for older and newer Macs, and cheaper than the 9800. Might even throw in some games with purchase.
