Video Editing: Is it time to upgrade my PC?

[Pyrofan]

I run a aerial photography business and do alot of 4k editing and rendering out special effects in Premiere Pro and After Effects. I currently have a two PC's, my laptop and tower. The laptop is decent at editing, but the tower is much better.

Here are the towers specs:
MOBO: ASrock Pro 4

CPU: i5-3570k

GPU: Powercolor R9 290 PCS+

PSU: CX750M

RAM: 8Gb of Corsair Vengeance

Case: HAF 932 advanced



So for the upgrade, I am thinking this:
MOBO: ASUS Prime X370-Pro

CPU: Ryzen 1700

GPU: Up for debate (480? 1060? 1070?)

PSU: CX750M

RAM: G.SKILL Ripjaws V Series 32GB (2 x 16GB) DDR4 2400 (PC4 19200)

Case: HAF 932 advanced or something smaller


I just cant decide if this is the best for video editing? So that leads me to yall, whats your take on this?

Ryzen 1700 and a nice 1070 with the memory you listed.

How much of an improvement can I expect?
