Best CPU for emulating games?

I will be building my first gaming desktop in about a month and need help with deciding on a cpu. I know a cpu doesn't add many FPS on games, but I will be emulating games as well. Such as on DeSmuME, PCSX2, and Dolphin. So which cpu would give the best performance for emulating between ivy bridge, and haswell? Originally I was going with the i5-3570K and I plan on overclocking the cpu I get to 4.2-4.4GHz in the future.
 
Solution
The i7s aren't actually binned any higher, and I've got an i5-3570k and GTX 670 that emulates wii games on Dolphin nearly perfectly, even after giving it perks such as native 1080p textures.

Go with a haswell i5 (I highly highly recommend getting a good air cooler and overclocking it) and a decent graphics card, and you'll be fine.
Haswell is perhaps 5% faster per clock than ivy bridge. But, on a "K", you generally can't oc quite as high.
CPU performance comes out as a wash.
That said, I would pick haswell, mainly because the Z87 chipset is a step up over Z77.
I would doubt that the hyperthreads of a 4770K would benefit you much over a 4670K.
But, if the extra $100 is not a big deal, go ahead and buy a 4770K because I suspect they are binned higher than the 4670K and can be safely overclocked a bit higher.

The highest singlethread performance you can get.
That limits you to intel. As I don't think most emulators support more than two cores there will be no gain going to i7 and minimal gain goming from i3 (though for heavy non emulated games the i3 may not cut it).

It won't be. Intel's sockets die after two generations of CPUs, and there isn't any point in upgrading just one generation.

Also, unfortunately not. Haswell is a miserable overclocker and puts out a lot of heat, so a 212 EVO or + will get you up to 4.1, 4.2 if you're lucky. But that's fine, and is still a fairly significant gain.
