you'd need a pretty crazy PC to be able to handle it, anyway i still dont know how it's possible to have such amazing graphics on a console. and no frame rate drops, either.
Give it 18 months or so and you won't need an insane sli setup to get the same graphical quality. Besides, Crysis at maxed out settings will probably look better than GoW anyway.
Co-op with a friend on a good FPS in front of the TV split screen style I can say holds some of my fondest memories in gaming, one that would get you more involved in comparison with a pick up and play game of soccer.
That is so true. I took my 360 over to my friend's house the day after getting it, and hooked it up to his brand new 42" Sony Bravia LCD TV. Played 8 hours of co-op straight and completed the game. It was extremely fun.
