A system to match an R9 390
So what I would do is to find a
PC Part Picker tool or the like and put in the R9 390 to see what CPUs would be a good match.
I think something like a budget 450 board and a Ryzen 1300x and 8GB of DDR4 RAM should be an okay match, but it won't offer much headroom for future upgrades on the GPU.
With the lineup from AMD being so close at different price points and some of the better value CPUs having such a range of selling price week-to-week and vendor-to-vendor it is difficult to recommend anything unconditionally. If you can find a Ryzen 1600AF (not the standard 1600, must be the AF version) for less than £90 this is still an amazing CPU for the price. Alternatives at the budget end of the market include the new 3100 and 3300 CPUs. If you can find the 3300 at £130, this is not a bad option. These are faster single-threaded (most games right now) than the 1600AF, but have less cores (maybe most games in the future). 16GB of DDR4 at 3000Mhz or faster will also avoid bottlenecking the CPU and is recommended now for some games.
Monitor upgrade
Unless you are exclusively playing games from 5+ years ago I would not consider upgrading the monitor resolution or refresh rate whilst keeping the R9 390. With this said I'm personally astounded by how monitor prices have decreased and resolution/refresh rate has improved over the last 24 months or so, and am very excited about one day being able to afford something like this:
