I personally don't like using PC's for any games (just my preferance) but I have never noticed any difference in graphics from an Xbox360, PS3 or PC. The manufacturer decides the quality of graphics in a game and the fastest graphics card and processor in the world won't make them any better. The only advantage I see in PC versions is that there is a lot more keys to add more stuff to use in the game (which is why I don't use PC's for games cause I can't remember all the features)

I don't see what all the arguing is about, it'll be a great game on any platform and everybody has their own preferences. All 3 platforms play games well and games are supposed to be fun.
