Hello i'm thinking about upgrading my GPU from a GTX 960 to a GTX 1060 but don't know if it would be a big enough difference considering my CPU isn't anywhere near the greatest. My CPU is the AMD FX-4170 I mainly want better fps in overwatch I play on low settings and want a stable 120+ fps. Would I benefit more from getting the 1060 which is the cheaper option or getting a new mother board and a i-7 CPU?
