I specifically bought an AMD card for my living room Steam box, and I've had way more driver issues with that computer than when it had an nVidia card (although there's also other software changes). Mostly: the audio hitches frequently when outputting via HDMI, and a many-year-old AMD driver bug where it will always prefer YUV to RGB when supported by the display with no kernel parameters or anything to override (this one is apparently finally getting fixed in 7.2 hopefully). That said, I've had some issues with the nVidia drivers too, and I much prefer open source ones, ceteris paribus.
