> In the $50 range you can get an R7 350, which promises 4K support (although I suspect that will be at 30Hz)

It supports 4k@60. It looks like everything with a GCN core does, so most 7xxx, most 2xx, and all 3xx.

I think the older Radeons only support 4k@60 over DisplayPort though, HDMI support for it is relatively new.
