I went with water + ud5. which I think is a good match. Classified on air would clock worse and cost the same amount.

Any links to that or is that just your experince in using both boards?
Thanks for the not-very-subtle out of context quoting. As you're quite right in guessing from my post, I don't have a classified.
My point is that UD5 + watercooling costs about the same as classified + air, and
given there is water involved in the former it is inevitably going to perform better with the ludicrously hot i7 chips.
In no way to contradict this by WJA96, but I think it needs to be added to
I could be reading that incorrectly, but in general, D0s are cooler than C0s as they need about 0.1V less to get them to the same overclock.
D0 is generally cooler than C0
at the same clockspeed as the D0 need less voltage to get there
C0 is generally cooler than D0
at the same voltage as the C0 draw less current at a given voltage
So if you're aiming for a specific speed, say 3.8ghz, the D0 is likely to be cooler. However if you're aiming for the most you can possibly get out of it at, say 1.4V, the C0 will be cooler though may also be clocked lower.
A side effect is that the D0 is more vulnerable to electromigration
than the C0 at the same voltage as the current densities are higher, which probably means it'll live for less time if run at higher voltage than intel specify. So the C0 is safer to overvolt. I have a suspicion that the consequence of all this is that the chips behave the same; for a given clockspeed and lifespan the C0 will need more voltage, but it can tolerate it better. However the D0 will need a lower voltage, and people will feel a lot safer pushing 1.4V through the D0 than 1.45V through the C0 just because the number is lower.
Numbers are approximate, refer to Black's equation or the more knowledgeable forum member death looms if required.
