Just answered my own question, all 6 on my new Phneom 1055T. Render the file that gave me BOD at only 30 seconds past time time (12:45) which is twice as fast as my only 3 ghz quad.

I got the 1055T because it was the only one I could find, guess AMD has discountiuned the Phenom line and since I have a AM2+ socket I'd have to change my MB and RAM if I could find one. I don't plan on OC the board but understand it does well upto 3.6 or so.

I'm a happy camper:)
