I am deciding on how to upgrade my system at the moment. I have an i7 2600 non k on an Asus P8H61-M LE/CSM motherboard with 16gb of 1333mhz ddr3 ram and a gtx 1060 3gb gpu. with my budget of appx $375 I was thinking of either doing an i5 6600k/z120 board with 8gb ddr4 or i5 7500 non k/h270 board...
