I have an iMac from 2009 with this CPU, and it still performs admirably for its age. Is it worth it today though? Not quite, like most of the early Core i3, i5, i7, and all the Core2 CPU's their viability fades by the day and its only a matter of time before they become unusable, but for now this chip is still alright and if you have an old machine laying around with this chip and wanna save some money you might as well restore it! [Mar '24 Randomgaming128]

MORE DETAILS

The i7-2600K Sandy Bridge processor is two generations old and nearly three years out of date.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