i7-3970x or i7-3930k
So on my new build ive been researching the cpu's quite a bit but dont know which would be more beneficial for me
So the top of the line i7-3970x looks pretty awesome but the price tag of $1,079 is assumed to come with the best i7 chip
The 3930k is basically the same chip just underclocked abit from what i understand with a price of $569

Will i get much more out of the 3970x over the 3930k for multiboxing WoW? Is it worth the almost doubled price?
Im looking to run at least 10 wow's on each of my good computers as thats what i can run on my current setup, but i also want to be able to fraps in highquality with my new setup without any system lag or low frame rates. Right now with i7-990x, 32gb ram, gtx690 when im running 10 box and frapsing it drops framerates below 30 on big fights. I want to keep free of the lag spikes i get from performance issues.

thanks
