yeah, me and DJ-Chris are actually gonna put out systems up against each other. My 2.5GHz XP-M against his 2.3GHz AMD64bit system. We both have 1gb of RAM and will both have 6600GT's. His is on RMA, mine has yet to come, but it should be interesting to see how a socket A will perform against a 64.
And of course I plan on OC'ing mine
But for competition purposes we will do stock first. He has XFX though while mine like I said will be an eVGA 6600GT
