Is it worth upgrading just those parts or should I get a whole new setup?

I have a i5-6500k at 4.5gz with a 1070 and I still get plenty enough performance. I guess it depends if you wanna stay with 1080p 60hz or not.

If you don't plan to change soon, you can just grab a new low-mid range gpu + 8gb more ram and be totally fine

Edit : there's a big gap between 1050 and 1070 btw
