The i7-2600K Sandy Bridge processor is two generations old and nearly three years out of date. The numerous owners of this superb processor should feel in no hurry to upgrade as it's still one of the fastest consumer processors, even by today's standards. The benchmark figures indicate that in terms of real-world performance this processor is only 5% slower than the third generation Ivy Bridge i7-3770K, not bad considering its age. That said new buyers will find both better energy efficiency and marginal performance improvements elsewhere[Feb '12 CPUPro]

MORE DETAILS

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]
