The i7-2600K Sandy Bridge processor is two generations old and nearly three years out of date.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]
