Why are you so hung up on WoW? Did you have a bad experience or something? And no, I am no WoW fan, it is far too boring...all the 'grinding' to get to the fun stuff.....nah, not for me.
Fact is, PC's are vastly more powerful, the DX11 games and the video cards running them are so far ahead of PS3/Xbox it isn't even funny.
What you seem to be a fan of is badly mad 'blockbuster' titles. The COD's, the Madden's, the GTA's. Those aren't 'games', those are big titles with no substance but because casual gamer can pick them up and have a bit of fun they sell like hotcakes.
I prefer gaming, in general on the PC. I really enjoy playing a game and then look up and think 'crap, where did the last 4 hours go?' and I just don't get that with console games.
I have been a gamer my whole life....I started out on a TRS-80, had several PC's and all the gaming consoles (minus the Dreamcast, which I regret). I enjoy games across all of them, but if I had to pick only one to live with, there is no hesitation, no consideration. It is the PC each and every time.
