i7 3820 not overclocked could bottleneck 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)?

An i5 wouldn't, bottleneck the graphics card, CPUs today are far more powerful than what is required for games. So not, there no worries APU an i7 bottle necking anything.

Ok, thanks. I was really impressed by these results http://forums.anandtech.com/showthread.php?t=2278579 where a 3930k performs 179 fps and a 2600K (similar to 3820) 156 fps at 1920x1080 with 690 gtx. That's a huge difference at that resoultion. Could that be a CPU bottleneck?

I'm pretty sure there isn't a CPU out there that won't bottleneck a GTX 680 SLI or GTX 690 right now...
