The single biggest determinate factor in the frame rate of games is the graphics card these days.
Until you put better graphics cards in the mac you won't get decent games performance.
If you only use your computers for games then buy a PC. There's no arguement, PC's wins hands down in the games market because that's the platform all the developers work on because it is the biggest market and makes the most money. The hardware vendors also operate in a different market this helps drive the cost down through commodotisation and economies of scale.
However the best price/performance ratio when it comes to games has to be a console.
As for IBM, the G5 and heat issues etc. consider this. IBM already makes the chips that power the nitendo game cube, makes the Nvidia GeForce FX processors and they are in a joint operation with Sony to make the processors for the new PS3. From what I have heard the chip shipped in the xBox 2 will be a 65nm part not the 90nm parts used in the apple mac G5's. It will probably be packaged differently and Microsoft will probably get quite a bit of say in what heat versus performance stats they want to achieve.
As for a multi processor system, most of the impetus in the chip industry is towards multi-core packages, ie. 2+ processors in a single package. This would make it considerably easier to put multi processors in the xBox 2.
