Possible CPU upgrade for GTX 1060 6GB3

Hey guys, I recently upgraded my GPU from a radeon 6800 to a GTX 1060 6gb because thats what i was told to get by others on here according to my specs. Despite this, the card doesn’t seem to be performing to its capabilities and I think it might be because my CPU isnt strong enough for it and I’ve noticed it hits 90C when playing things like CSGO.
