I think 4.2 is a safe bet with those chips, and under water. It is probably more difficult to stabilise on a two-way board, but not terribly so. Maybe do 4.0 and leave turbo boost for an extra jolt on cores that need it?
Can't see that chipset drawing too much juice, coming form a server end of the market and only a single GPU to start with. A good branded unit should pull you through, as most reputable PSU OEMs tend to underrate their products, and hence there is more real power in them than on the label, albeit at lower efficiency ratings.
How demanding is your water pump for power?
Heh, well using turbo it would be on all the time

Not worried about the pump, more worried that the PSU is at least 650W, I always buy decent PSU's. But this board needs two 8pin connectors so I may have to invest in a new PSU and put the old one on MM.
Can't remember what I have in the machine currently
