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 and 8gb ddr4 or even a ryzen 5 1500x/b350 board with 8gb ddr4 ram. I mainly use the computer for gaming so streaming/video rendering or other multi threaded applications are not really used. The other option I thought of was that if my current i7 2600 non k cpu wouldnt bottleneck a gtx 1070 then I could use the money to upgrade just the gpu. Can anyone help me make a good decision here?
