I have a Ryzen 1700 with an RX460 (it was the cheapest card from the same supplier that would drive my screens) and its been flawless out the box with the open source radeon driver. In fact I didn't have to touch any of the graphics at all, more by chance than anything left screen was left/right screen was right (it's 50/50 and I end up with it the wrong way around 95% of the time). I'm driving 2x2560x1440 Dell's and it's buttery smooth. I don't game on that machine (it's a work desktop I built). The open source radeon driver has improved massively in the last year or two.
