The PC will obviously be better in terms of graphics. for the price of one 4870x2 or gtx 280 or gtx 295 you could buy two xbox 360s. so the pc obviously has the edge in graphics. especially considering most are played with AA, AF, and higher resolutions than the consoles support (the psr reality synthesizer is equivalent to a 6800 ultra i think they said). i really don't care about graphics as much as i do about games and fun, since they're all so similar looking.

The DX 10 graphics are slightly better with shadows, water, and creating a "puffy" effect in the clouds, but besides that there isn't much difference. Between Very high and high, however, there's a huge difference. However, DX 10 adds some motion blur. In all the other sites I've looked at, Vista drops frame rates by usually 20 frames or more. I wonder why this didn't happen with the Gamespot tests. Even an Nvidia 9800 GX2 in quad sli can't play Crysis at over 25 frames per second on very high settings (for reference, Tomb Raider: Anniversary is at over 400 frames per second on the same system).
