Unless there's a specific reason why you couldn't get the 3930K.
A proper 3770K can be quite a bit faster. 3770K can get to 4.7 on good air cooling, 3820 about 4.5-4.6. Factor in that 3770K is faster clock for clock (my 4747MHz 2600K was on par with my 4487MHz 3770K) it's really a reasonable difference.
I certainly notice the difference between my 2600K at 4.7 and 5.2.
Really? I struggle to really see the difference (In gaming, that is) between my i5 at 4Ghz or 4.5Ghz. Obviously, I would in other areas but yeah...And yes, you likely could. (Or a 4930k) People do that type of upgrade all the time, I know one guy whose buying an i3 Haswell with plans to get an i7 Haswell or Broadwell later, even if he has to buy used.Also, the average clocks for an 3820 are 4.8 here?
The i7 3770k is a tiny bit lower but you're talking 20-30Mhz at most. Might not be stable clocks and just for validation, but who knows.
And besides, if you want to run CFX/SLI and a RAID card (Or anything that has a lot of PCIe bandwidth requirements) then an 3820 is going to beat an 3770k there simply because it has more lanes, really you're talking a tiny loss in performance and a tiny bit extra for the ability to have more RAM, more PCIe lanes and an upgrade path.
