I upgraded my TV box to an i7, leaving me with a Phenom II x4 955 lying around. My youngest son is running my old Q6600 (OC @ 3.2GHZ) setup and I was wondering if it would be worth it to upgrade his rig with it? He plays lots of games. I'd hate to have to tear his rig apart and reload windows if its not gonna make much difference. I allways left the X4 @ stock, but will OC it if I put it in my sons comp.
