I see a comment about upgrading the cooling system for a few of the suggestions, is this necessary?

If you keep the CPU, you can get loads of extra performance simply by dropping in a new, faster gfx card. If I read the nameplate on the PSU correctly in the picture, it appears you have a cheap, low quality "500W" PSU with light-weight +12V rails. So the GTX 1060 3GB would be the best card I would suggest you can safely use. Should alloow you to play any game at max/near max settings at 1080p.

Your motherboard is a low-end AMD 760G model. A 95 watt FX CPU will be okay with it.

The FX-8300 is not needed in my opinion, just get a better GPU like 1050Ti or 1060/RX480.
Also, I wouldn't risk overclocking on a 760G motherboard.

1. Better GPU
2. Better power supply
3. Better CPU (especially if you want to play ARK)
4. A new SSD (for faster load times)
