Question Which GPU to go with ryzen 7 2700x


Sep 9, 2018
Hello, I got a ryzen 7 2700x and I believe it's time for me to get a new GPU as well.
I currently have GTX 770 4 GB, and even though it's currently pretty much enough for my needs, I think I'll just get myself a newer GPU as well to go along.

My usecases are basically CSGO/PUBG(on a rather low resolution, 1440x900), a bit graphic design and that's pretty much it..I don't really need all that much tbh.
The thing is that now I'm not sure what I should really get, I'll probably get a second hand GPU, I could get an RX580 8 GB for around $85.
I could also get a GTX 1070/GTX 980 for around $200, and maybe a GTX 1080 for around $300.

I'm quite puzzled with what I should get for my needs, so would love to hear some suggestions :)

In case it's relevant, my other specs are:
ASRock X570 Phantom Gaming 4
2x16 GB RAM
800W gold PSU

Anything else that's relevant? Thanks! :)
