xbox360 is 128bit processing architecture. And the gfx or cpu got tassellation feature. That feature can make a less than 1 thousand polygons model looks like a 10-20k polygons one. Dx11 is going to implement this feature. The game is prefectly optimized, so it is smoother than pc. And why ps3 did badly in multiplatform game? Becos the developers failed to optimize the game, becos developers did said that ps3 dev kits are just way harder to use compare to xbox360, even square enix said xbox360 dev kits is fun and easy to use.

So the debate will go on until the centre of the galaxy. Console has their own good, while pc has its. So conclusion is, comparing pc and console is like compare a car with an aeroplane, different category, although serve the same purpose. Just play watever u like and live life the best.

Btw, i dont really agree on this:

In order to play a PC game (multi-platform) with the same image quality as on console, we don't need a super spec.(we don't need a quad extreme -yes).

Sometimes u do need a super spec becos they arent optimized well on pc
