Full HD playback will give you no issues, same cannot be said with full confidence for AMD hardware. Look I will be frank, I have less idea about AMD chipsets than Intel, the APU 5350 has R3 graphics, which technically supports passthrough, but no idea about AM1M-E. Very frankly I would never trust AMD hardware on HD audio passthrough and quality videoplay back, specially 3D, always driver issues. With windows might not be problem, but why limit my self.
But none the less if it does give you problems, you can always get a dedicated GPU like GT710. Also I gave a quick look at the Mobo specs, looks like it only offers 4 lanes of PCI-Express 2.0. (AM1 chipset). This, means the discreet GPU will
not be running at its full bandwidth. Even though it does have a physical x16 slot. Not sure if this concerns you if you will be using it only for HD passthrough purpose and watching 1080p videos. Should'nt be a problem I guess. (But for me why would I pay for a hardware, even though its cheap, and underutilize it or not utilize it to its full potential ...
