That's just crazy! Whatever do you need all that processing power for?... I have a 2.53GHz Core 2 Duo that handles everything I throw at it, plus is more than enough for video editing and graphic design. Furthermore I can play any game with my cheap ATI HD4850, most of them I can max out.
I used to be into upgrading every year or so but have since come to realize what a scam it is with silly incremental upgrades; games and programs don't even keep up with it.
