i5 6500 or i5 6600k7

Hi guys ! I’m building a new PC with: GPU:EVGA GTX 1060 6GB RAM:8gb Hyper X Fury DDR4 2133Mhz Mobo:Asus H110M-D – 6th Generation DDR4 MotherBoard Cooler: Hyper 212X HDD: WD 1TB Just couldn’t decide on which CPU to pair with my 1060- i5 6500 or i5 6600k. Also, how much W PSU would be recommended for this build given that I’ll use it for gaming With the h110 motherboard, there isn’t much point in paying the premium for a K series CPU.
