If there is any chance whatsoever that you may decide to overclock your CPU then it makes a lot more sense to go for the 2600K "K" version which, thanks to its unlocked clock multiplier, is a lot easier to overclock. For the few extra pounds it costs, I would recommend taking the K version just on the off chance because there are easily 10%+ performance gains to be had. Otherwise this is still a superb processor and still holds its own against the i7-4770 which is its two generations newer replacement. [Feb '12 CPUPro]

MORE DETAILS

The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]
