Phenom II is very much outclassed. It takes two instances of mfaktc to max out the 460. One might suppose that it will take at least three for the 570. Hence the expectation of running one of the cards on CLucas. Stress testing will affect how I assign things. I guess another option would be to add CLucas on the 570 to fill out spare cycles.

Heat will be another issue. If all else tests well, how well I can exhaust another 219 watts worth will determine how hard I can run things (at least until Autumn or when the A/C is running. This is aggravated by having to remove a double-slot centrifugal blower to make room for another GPU.

I am fairly confident that a PC Power and Cooling 650w supply is up to the task. It currently draws 375w with 2x mfaktc on the 460, 3 P-1 workers, and an LL in P95. Anadtech review suggests that it will not live up to its "Silencer" moniker under a 92% load, though, especially at 80+ F ambient.

EDIT: On the other hand, at these temps there is already one loud fan in the case and two moderately loud fans. Add the room circulating fans' noise and I may not really notice one more.
EDIT2: On the gripping hand, I could stick the 570 in my partner's i7 920. (...not really. I could not run it there full time, I think, without complaints.) Besides, I want to see if I can deal with situation in one box.

I was being _very_ diplomatic. :)

Hey if anyone can find a suitable use for them - go nuts.

Even a 2500K beats it more often than not. My ancient Q6600 beats it in 2 tests.
