I have a gaming PC, sure it looks great. PC is my preferred platform, but I can't stand the "PC gaming master race" mindset.
I've been playing Halo 4 on my 360 and it looks more than acceptable.
It COULD look better, but it doesn't need to. The gameplay is great and that is what matters most.
A game could be photorealistic and still be horrible if it can't hold your attention.
Its a bit of a rant. Not trying to start a flamewar, just want to know your opinion on how much graphics effect the quality of the game.
