What is cpu?
The Core i5-4690K's base clock rate is only 200 MHz faster than the Core i5-4590's. However, the K-series' unlocked multiplier is a must-have for overclockers looking to unleash significant performance improvements. It is for this reason alone that you'll want to consider shelling out an additional $50 beyond Intel's more entry-level Core i5. If you don't plan to overclock, there's no reason to spend any more than $190 on the Core i5-4460. The best cpu is the Intel Core i7-5930K Haswell-E 6-Core 3.5GHz LGA 2011-v3 140W Desktop Processor BX80648I75930K that costs £637.99
