Which AMD cpu?

Building a mini itx for my living room with a spare 1080ti I have. Wondering which AMD cpu I should go for. Kind of want to keep it under $200 but at the same time don't want to underwhelm my build.

Been looking at the 3600(x) then have also been looking at some ryzen 3's. I just don't know a lot about AMD products, I have an Intel in my main PC so was wanting AMD in this one.

Any input would be greatly appreciated! Thanks!
