The i7-2600K Sandy Bridge processor is two generations old and nearly three years out of date.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 third gen Ivy Bridge Core i7-3770K can't really be described as a consumer orientated processor. With 8 threads and four cores its capabilities are better aligned to server use. For price insensitive consumers that want the best of the best, this is currently one of the fastest processors available. The PassMark Single Thread score of 2080 points put the 3770K right at the top of the pack in terms of raw processing power and real world performance. The GeekBench and PassMark scores of 17210 and 9653 are within 20% or so of the best we have ever seen. Despite the near record breaking processing throughputs the 3770K is only rated at 77 TDP, which is also very reasonable by historical standards. For typical consumer use there are better value propositions out there. [May '13 CPUPro]
