4790 (K) Has A Better Internal Tim And Thus Better Temps (Which Translates To Better Overclocking Potentially).
If you're willing to delid, go 4770 (k) and. The 4770k has 4 physical cores which allow it to process four streams of instructions in parallel. The big difference between the 4770k and 4790k is the interface between the ihs and die, as well as 4790k's being built later and on a slightly more mature process.
Comparing The 4770 And 4770K Shows That The 4770K Yields 14% Higher Processing Throughput When Overclocked And Also Costs 14% More.
Not sure if getting another cpu, board and ram are gonna be worth the money and effort. I had the 4790 first though, just needed another cpu. So obviously the faster chip that costs less is the better choice.
Most Optimistic Are Early June And Pesimistic Push It.
A delidded 4770k is arguably better than a 4790k. These improvements (~4%) are marginal and practically impossible to discern in day to day use. Official release date is not out yet.
The 4770 Runs At 3.4Ghz(Turbo To 3.9Ghz) While The 4790 Runs At 3.6Ghz(Turbo To 4.0Ghz).
I don't even find the 4790 worthwhile over the 4790k whether you're overclocking or not. 4790k should run 4.0 ghz stock and 4.4 ghz turbo boost. 4770k running 3.5ghz stock and 3.9 ghz turbo boost.

There's no shim needed, you just center the lid on the die and when you clamp the chip into the socket, it locks the lid in place. Amd hasn't been able to compete with intel on single threaded performance for several years. The 4790k features an improved thermal interface which enables it to dissipate heat more efficiently than the 4770k.
