I am in the process of turning an older PC into a Steam Stream Box for my living room (My office PC does the heavy lifting for gaming and sends it to my older PC in the living room). I would like to use a spare R5 235X I have, but the older PC is currently running Ubuntu 14.04. I know there is support for this OS for AMD drivers, but I cannot find my specific card listed. Could I use a driver that supports similar cards? Any help would be greatly appreciated.
