Thats a rad ass system. I sure hope that proc is a Winchester. Runs cooler and consumes less watts. Bet that setup put a 1000 hole in ur wallet.
Are you planning to go SLi? Im sure you need the ATX 24-pin PSUs even though some say you can use an adapter. it wont be constant voltage and end up firing your system.
Anyrate, glad everything worked out. heard a lot of problems with that ASUS mobo, but tight rig.
