If there is any chance whatsoever that you may decide to overclock your CPU then it makes a lot more sense to go for the 2600K "K" version which, thanks to its unlocked clock multiplier, is a lot easier to overclock. For the few extra pounds it costs, I would recommend taking the K version just on the off chance because there are easily 10%+ performance gains to be had. Otherwise this is still a superb processor and still holds its own against the i7-4770 which is its two generations newer replacement. [Feb '12 CPUPro]

MORE DETAILS

The Intel Core i5-4670K is the latest middle tier desktop processor from the fourth generation of Intel's Core range codenamed "Haswell". In terms of raw performance this processor slightly bests its predecessor the 3570K achieving approximately 10% higher server benchmark scores. In terms of real world performance the single core improvements are more relevant as more than two cores are rarely used for most typical consumer tasks and these have also improved by around 10% over the 3570K. It's not all good news though as the price increase of 14% more than offsets the performance improvements. This processor currently represents approximately the same value for money as its predecessor, the i5-3570K. [Jun '13 CPUPro]
