BioShock, Gears of War, and Mass Effect also use Unreal Engine 3 yet preceded Unreal Tournament 3's arrival by a few months, and almost a year in the case of Gears of War. The games may all use the same engine, but they have very different hardware requirements. Whereas BioShock requires powerful hardware to run, Unreal Tournament 3 doesn't leave anyone out of the fun. Mid-range CPUs and video cards from two years ago can run the game just fine, and with marvelous image quality. Of course, if you want more performance, higher resolutions, and antialiasing, more power is the way to go.
