Default i7 3820 or i7 3930k for 680 gtx Sli?

I am going to buy a new PC with 680 gtx Sli. If I equip it with a i7 3820 not overclocked (I.e. standard 3,6 Ghz), could the 680 gtx Sli be limited by the CPU? Would a i7 3930k be a better choice? Worth spending more money? In a nutshell, if I decide to equip my 680 gtx Sli with a 3930k rather than a 3820 what fps boost range could I expect to gain playing at 1920x1080 all filters ON (AA, AF, AO and so on)?

I don't think you're really going to notice a FPS difference at that resolution. The i7s aren't limiting SLI at all so you really shouldn't have any issues with the i7 3820 running your dual 680s

The 3820 will easily do the job, and you'll be able to upgrade to IB-E anyway down the road when ever you feel like doing so.

Thank you very much for your clear explanations. I will go for the 3820 then.

mind you, if you were trying to run everything at its bleeding edge inlcuding graphics cards being overclocked, the extra cores and unlocked multi on the 3930 would allow that much more overhead for you to fiddle around some.

But, most folks I know are not overclockers, so, a 3820 is plenty powerfull enough, 4 cores 8 thread at 3.6Ghz is anything but slow/weak.

I agree the i7-3820 is plenty for what you have and two GTX-680's is more then enough even two GTX-670's would be plenty.The i7-3820 overclocks great nearly all of them will do 4.6gig with no problem ,if you are lucky it will do 5gig .Mine will do 5gigs but I have to up the voltage more then I want and besides as was said the Ivory-Bridge-E will be comeing out probbaly in Q1 of 2013 .That is the only upgrade I will do next year even tho I no it is not needed.

I think Ivy Bridge-E will be more like Q4 2013 than Q1.

I don't know about that one intel is sticking with their tick/tock schedule pretty well and approximately 8 month delay would be pretty long.

A single GTX 680 can handle pretty much everything maxed out at 1920x1080 in pretty much every game. i recommend picking up a nicer monitor so you can actually see the beauty your GTX 680's are pumping out.

I guess you didn't see the leaked slides that came out this summer...

With AMD's "we don't want to play anymore" attitude on the high-end desktop CPU's, there is no incentive for Intel to rush these out anymore.

If I use 1920x1080 60Hz display (not 120Hz), can I see the difference between e.g. 90-100 fps and 60 fps when I play video games with Sli enabled? Do they look smoother even with a 60Hz display when reaching 100 fps instead of 60 fps?
