Goku: Every system has multiple processors. There are processors on every single board on a system. There are proccesors on sound cards, video cards, and almost every other card in any system. The X-box has a proccessor on it's video card that handles video, 250 MHz compared to Gamecube's 162MHz, it also has a proccessor on it's sound card to handle sound, like every type of system. Also Nintendo has admitted that the X-Box is far more power then the gamecube. Also the reason why you can't run an N64 emulator on a 200mhz machine is because it is completely different hardware, in which the games are specifically designed for, so you need more power to compensate for that.
