The 6400+ is almost performance competitive (but not power competitive @ 125W vs 65W) with the E6750, and costs $75 more than the E6750 which includes a heatsink. You can't compare AMD's current high end desktop processor to Intel's high end because AMD has nothing that performs above the E6750, while Intel has several faster processors.
I have a 6400+ in my shuttle xpc, I bought it because i figured the shuttle wouldn't oc that well. I found one for $230 so i didn't have to pay the 280
Where did you find it for $230 and does it have an unlocked multiplier like a couple of the reviewers stated at the 'Egg? If I can get one at that price with an unlocked multi, I'm there!
