The i7-2600K Sandy Bridge processor is two generations old and nearly three years out of date.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 Intel Core i3-7350K is Intel’s first unlocked i3 processor. The base clock of 4.2 GHz on the 7350K is matched only by the flagship i7-7700K. Consequently for desktop applications and the vast majority of tasks that rely primarily on single core performance the 7350K excels. The i3-7350K’s key feature is an unlocked multiplier which should allow a comfortable overclock (on air) to 4.8 GHz. This makes the 7350K far better suited to desktop workloads than any other non-K CPU. The Achilles heel of only having two physical cores means that for tasks that can use more than two cores such as video encoding or software development, the 7350K lags behind its quad core counterparts. For typical desktop computing such as email, browsing with multiple tabs, office documents and playing the majority of games the i3-7350K is a viable option, but at current prices it’s bested by both the i5-7600K and i7-7700K which offer far better value for money. [Jan '17 CPUPro]
