Clock for clock is about the same as a 2600K/2700K, but does not go above 4.625-4.75 GHz as easily on air or cheap closed loop WC, as it has a partially locked multiplier (43x).
You overclock with block/strap + Multiplier with the SB-Es, so you do 125MHz x 37~38 multi - this is the cookie way for the most of us.
The only advantage is that it has more cache, that is already good enough in SB/IB LGA 1155s, so it takes the lead here and there.
The Ivy (3rd gen 1155s) are generally faster clock for clock, but it lacks expand-ability (if you want to go more than 4 cores, more than 32GB of RAM and tri-quad SLI/CX) and future-proofing - IB-E will still be s 2011 with the socket and current mobos still supported well into 2013-early 2014 with new CPUs. LGA 1155 is phased out with the next gen of intel i5/i7s being LGA 1150.
For general computing and gaming, the 3820 has no real advantage over the 2600K/3770K.
It just buys you the option for a 6-8 core upgrade in the future. It is also cheaper to buy (comes with no HS tho), so if you catch a deal from Microcenter or the likes (used to come with $50 savings if you would bundle it with a X79 mobo from them, as I did), you actually pay pretty close to what you would pay for a LGA 1155 i7 + a decent Z77 mobo.Edited by pcfoo - 9/26/12 at 11:31am
