What is your goal? 1080p, 4k, 1440p??? What is your frame rate goal, 60fps 120, 90, 144?? What is your display and refresh rate?? We need to know all of this to give you a real answer.
If you want a good overall system for 1080p 60fps+ gaming on max settings I would look into this.
Ryzen 2600/x (depending which is on sale), gtx1060 6gb or rx580 8gb, 16gb ram, 240gb solid state drive, decent motherboard for roughly 100$ from Asus, msi, gigabyte and asrock. 550w+ power supply.
If you want to go higher you can just move up the video card to a 1070ti. This would be for playing at 1440p max detail 60+for. The other system can do 1440p 60fos, but not fully maxed out.
