Looks similar to my old config except my 1060 had 6gb. I'd say this is pretty balanced, if you upgrade the GPU you'll get bottlenecked by CPU, at least in my experience that was the case. I guess a smaller GPU upgrade (say, to a 1080 Ti) could work but I'm not sure it's worth it financially. I'd say keep it as is.
