I don't suppose I could pique your interest in PC gaming....
But seriously, it's the best way to game these days. To say nothing of Steam, which is an incredibly cool way to play, PC has by FAR the best graphics, the most control options, and an online experience that's arguably better than Xbox Live (for free).
With the next iteration of graphics cards, there will be absolutely no comparison between PC and console games. The 4890/285 series of cards from ATI/Nvidia have given the PC a wider than ever graphical gap. PCs will soon be able to run games at high detail levels that consoles cannot even load in a basic form.
