I'm thinking it may be beneficial to check some other benchmarks. I don't know how userbench gets their results but their info is off. The 4690k is 3.5 (3.9ghz turbo) and the 4770 is 3.4 (3.9ghz turbo) so they both turbo to the same clock speed. Userbench reported the 'best' bench as only 3.4ghz. What happened to the 3.9ghz turbo? Even when all 4 cores are active the 4770 moves to 3.7ghz, not limited to 3.4.
The 'best' bench for the 4690k reported 4.95ghz which is a helluva overclock. Don't expect anywhere near that unless you're willing to go out of the realm of safe vcore when overclocked purely for a bench score, it's unrealistic. 4.5, 4.6, maybe 4.7 (if it's a better overclocker) for daily use is more realistic.
As others stated...
