2600k, 3930k, or 3770k the best CPU option for crossfiring 7970s?

So, I'm planning out some just-for-fun upgrades over the next month or two, and would really like to pick up a MSI Lightning 7970 to pair with my XFX in crossfire. However, my phenom obviously isn't up to snuff for that sort of work, so I need to upgrade my CPU and motherboard.

My current thought was to wait and get the 3770k, but I've heard some people say that it just isn't going to overclock as well as the 2600k and I should get that instead. I've also had some people tell me to get an LGA 2011 mobo and CPU as well, though that's a lot more money for from what I can tell not much more gaming performance :??: 

So - any thoughts for this? I plan to OC as far as I can on my 212 Evo - don't really feel like picking up something like a Noctua DH-14 at the moment to just get a tiny bit more CPU overclocking room.

MY PSU is a Corsair HX750, so I also like the idea of Ivy Bridge consuming a bit less power than Sandy, since an overclocked CPU + 2x overclocked 7970s is going to be pretty taxing on my power supply. Pretty sure that my current CPU OC draws wayyyyyy too much power (some reviews had a 4 GHz phenom x6 eating up 225+ watts) to safely pair with two 7970s that are also both heavily overclocked, though the HX750 is kind of a beast, so I dunno.

First of all no point in getting an i7 if your just gaming. An i5 will do just fine. SB-E is meant more for workstations and servers.
As for how well ivy bridge will do no-one knows as their not out yet. You'll have to wait.
Last I heard z77 mobos due out 8th April and quad cpu's ie i5 and i7 due out April 28th.

I've heard from a lot of people that well threaded things like BF3 MP take advantage of the extra threads... I don't mind spending an extra $100 to get double the threads, even if it only benefits in a couple games.

Yeah I don't think it's to do with the cores, I think it's more the hyper threading doesn't work so well with bf3. http://www.dayonepatch.com/index.php?/topic/34016-how-d...
My advice would be to wait for ivy bridge and see how that does. If your willing to fork out the extra money for a chance of a few extra fps then go for it and if you get stuttering etc then you can just turn off the HT. however you then effectively have an expensive i5. It's your choice.

I'd simply go i5-2500k and spend the cash saved on a very nice cooler.

Most games that benefit from more than 4 threads barely benefit.

I'm sure you'll be pushing full frames in BF3 w/ 2x7970 and CPU @ 4.5ghz.

Sounds good. Thanks for the replies guys. I'll wait for some Ivy bridge reviews (rumor has it that reviews will go live on the 8th) and then decide from there. Depending on pricing and availability I might get the IB successor to the 2500k (35xxk), but if they release the 3770k only then I'll just get that assuming reviews are good.

Maybe if IB reviews are lousy I'll just get the 2500k... I live near a microcenter and could pick up a 2500k + good mobo for ~$300. I'm really worried, though, that better threaded stuff is just around the corner in the form of Unreal Engine 4 - that's kind of why I'm willing to get the hyperthreaded processor.
