If I want to play the new Wolfenstein, or Watch Dogs, or any "new" game, chances are my 2 year old PC

My 5-year-old PC, which was nice at the time, hasn't hit a problem yet, with the exception of some games from the 90s. How many console games from the 90s does the XBox 360 take?

If I want to play a new game with all the dials turned up to 9 (or 11)

That's an unfair comparison, because the XBox most certainly, most definitely, and most absolutely does not have 'all the dials turned up to 9', let alone 11. The simpler, coarser graphics on the xbox are a common meme that's made fun of.
