I guess the big console marketing move got to you. PC is current gen AND next gen. There is no such thing as a dividing red line between "current gen" and "next gen", they are just consoles with more hardware power, just as the PS2 was light years ahead of the PS1. And even though a core 2 duo may not be able to compete with the seven cores in a PS3, there are no games that require that kind of power yet. Besides, graphically, I'd bet two 8800 gtx are better than anything these "next gen" consoles have to offer, and Directx10 (and future releases) are PC exclusive, at least for the moment. In a couple of years, a top notch PC will be better than these consoles in every department.
And yes, the PC version is exactly the same as the Xbox 360 and PS3. Don't believe console propaganda.
