This is why you buy a computer and don't even mess with a gaming console. It's true you will spend more but you have a very multi purpose entertainment system, one you can sell a wife on. I built a very high performance computer for $1200 building it myself. Music, Videos, applications, internet, and gaming. You should be able to sell getting a computer to your wife/gf, I was. Once she saw the functional value and free entertainment she can't live without it
I now game from a recliner on a very fast PC on a 70" LED TV. It's completely BADASS. So much better than a console, it's not even funny.
