I went ahead and picked up a i7 7700k, but based on what I've seen it was never intended to be a game changer. It seems like it was just a "perfected" i7 6700k. Thus the reason it can hold a higher base clock rate, "optimization" as the final stage of Skylake so this didn't surprise me at all. I'm upgrading from an older i5-2500k so I felt it was worth it, but definitely not if you were expecting a big jump from the 6700 to 7700. Nothing wrong with the 6700, but the 7700 sounds like it was just the last love song to the Skylake architecture before Cannonlake. It is probably little more than "7700k can OC with more stability than a 6700 plus new bells and whistles any new chips gets". In short, the 7700k seems like it was always going to be a 6700k mkII.
Still, I was more disappointed we didn't get the 1080ti... now I have to wait
