Well, I suppose if you can find a PC running on 3 PowerPC processors and a graphics core not yet released for PC's, than yeah. Otherwise, you're stuck buying mister big-brick.wtf.
those are so damn big, might as well go buy a pc and stick it in your living room.
I'm currently not to impressed with the 360's games, though. Quake 4, well, that's already available for PC. The game just uses the Doom 3 engine. I have yet to see anyone make use of those super-awesomer system capabilities
