Please remember though that although the XBox 360 has 3 processors running at the same time, only one of them will be dealing with the actual graphics and running of the game. One of the others will concentrate on the music of the game, and the other one will actually run the XBox 360 with it partially leaning towards to interface and DirectX or OpenGL. Just like your's and my dual core processor, only one processor can run the actual graphics and main parts of the game. So it will not have the combined power of all three processors, but don't get me wrong, it is going to be FAST. Much better than any "high street" PC for sure.
I'm starting to wonder what seperates a console from a PC now. I mean yeah, PCs are multi-purpose machines, that have operating systems and cost a hell of a lot more than a console. But I mean, the new consoles are releasing mice, keyboards, optional hard drives, and they already have CPUs, RAM, PSUs, and BUS modules ( a simplified motherboard) and the basic fundamentals of a PC. The advantage is that you can get a massively powerful console for the price of a top end PC graphics card
I spent £1500 on my new computer, and yes, for £209 you can have something that will blow my PC out of the water. That's life, but why complain when you can do pretty much anything you want to on your PC for the moment?
Personally, the PS3 will own EVERYTHING when it comes out, and it is THE next-gen thing to buy. Nothing is going to come close to that, which is why Microsoft sped up the XBox 360 for a Christmas release as it will lose out indeffinitely to the PS3 when it is released. Unfortunately, Nintendo are going to fall behind the two big contenders yet again with a late release, especially with it not being any better than the PS3 with less games, and targeted at a younger audience.
Anyways, back to the point. Yes it owns your PC and pretty much any PC out at the moment (with exceptions of course, but the PCs that can beat it cost AT LEAST 10 times more than the XBox 360). It's a shame you can't get all the hardware within these awesome machines for the same price! Then we'd all have a minimum of 3 processors and own any game out on the market for years
