What to upgrade?

Solution
A Z170 would be nice for overclocking, but motherboards are more for features than raw performance. You're unlikely to get much more performance out of it other than what you get from an overclock.

Honestly, the PSU is what I'd replace. That's EVGA's very budget, entry-level PSU, more suitable for powering office PCs and bargain-basement 750ti builds, certainly not anything with a $500 GPU in it.
