Soooooo...Should I just get a SB i2600k with a ASUS z77 Sabertooth if I want to overclock? or should I still wait for Ivy Bridge?

Good question. If you are going to stick to normal o/c (say 4.5GHz), IB is the better choice. If you are going for the gusto, 5GHz+ water cooled, SB or SB-E is the way to go for now. If you choose SB, you may find that IB becomes more efficient the more they tweak the chip so upgrade a year from now?
As time progresses, there is a good chance that IB will be tamed as for good heat flow. Remember that this is Intel's 1st crack at 22nm technology and it will improve over time.

Ivy Bridge is still going to be faster than SB even at lower overclocks.

From some of the reviews, it may be more efficient but it runs hot as hell, so it would seem that you would really want to lower the speeds more which then it would be even less effective no?

Bows deeply... Thank you Brad.

The best site so far is at Tweaktown:

They have run through the numbers and, indeed, thermal barriers limit the o/c of their chip as the temp quickly goes stratospheric above 4.8GHz. Hopefully, it is an engineering sample and that the production run is more forgiving. We will see on Monday.
At least I know what I should expect now.

C'mon, Graphene! Your time has come! Save the world from overheated, water cooled silicon madness!

From what I've been looking at, IB doesn't scale well thermally with higher voltages. 4.8 seems to be the limit with something like the H100. But on the plus side, 4.8 IB = 5.0-5.2 SB. I'll be moving from my Athlon X3 to SB-E and then on to IB-E. I was holding out to see whether we'd see 5.2 on IB but since the answer is no, might as well trade 7% lower clock-clock performance for 2 extra cores.

I like how we get some benchmark information on air cooling; paints a much more realistic picture than we usually get; or am I the only one not running liquid Nitrogen/Oxygen/Helium over my processor?

Expect Liquid Nitrogen tests in a few days.

Speak for yourself Steve, there's nothing I enjoy more than standing over a 24hr Maya render with a cup of rare, expensive, and extremely dangerous sub-zero liquids in one hand and a nice warm coffee in the other. Stable, dependable cooling = boring. You don't know the meaning of overclocking till you need to go to the hospital for a finger amputation. At least Intel still understands the importance of the thrill...

although I'll be sticking with Sandy Bridge, personally.

decently sized punch of salt... sounds painful.

A punch: like a pinch, but bigger.
