I already own, and FM2+ Motherboard and I was thinking about doing and upgrade to the cpu, but im not sure whether to buy the X4 860k or buy and i3 6100 + mother board + 8gb of ram, since it would be significantly cheaper to just buy the 860k, I am looking to use this with my R7 370, and to play games such as Battlefield 1, FSX, the witcher, and overwatch (though I dont really need them to run a max settings, medium would be fine)
