I know this topic gets tossed around a lot but to be honest, with Apple looking to promote more Mac compatible games and the iMac not suiting most gamers' needs... here's how it should of been done:
Take the Mac Pro, reduce it to like half its size give the body a black carbon fiber finish with the front plate being gun metal gray. Still preserving the dual optical drive bays (or one in this case) containing Blu-Ray (back in the day, they said Microsoft would push HD-DVD and Apple would push Blu-Ray) Then give it new Quad Extreme Chips (two sets for gamers) and one for the beginners of professional needs; a Quad Xeon chip. Next would be a max of 8GB of DDR3 RAM, Two hot swapping hard drives just like the Mac Pro has, and then here's the nitty gritty of the controversy of them all... video cards.
Model 1: Would have the Nvidia 8800 GTS
Model 2: Could have the Nvidia 8800 GTX
Model 3: For the professionals, Nvidia Quadro FX 5600
