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]

The i5-7600K targets high end gamers, it sits just behind the flagship i7-7700K in Intel’s Kaby Lake lineup. The 7600K will likely be the most popular gaming CPU of 2017 (some competition from AMD’s upcoming Zen/Ryzen CPUs, would be very welcome). Comparing the 7600K and 6600K shows that the two processors are very closely matched and comparing the 7600K vs the hyper-threaded 7700K highlights the relative strength of the 7700K for workstation performance. There are no significant architectural differences between Kaby Lake and Skylake so, when fully overclocked, the two generations should perform similarly but Kaby Lake offers faster base clocks, improved speed shift technology which helps CPU responsiveness, and better integrated graphics[Jan '17 CPUPro]
