The timing of this video is really strange. AMD sponsored a build for an APU that's going to be outdated in two weeks on a socket that's going to be outdated as well... Huh? Why not build on a FM2+ MB and speak about the A10 as a stand-in for the "Kaveri (tm) APU that's coming to a BestBuy (tm) near you!"
If you're buying an FM2 motherboard, then you might as well buy a cheap Athlon processor with cheap RAM. If you choose wisely, than can give you ~ $100 you can put towards a discrete GPU. Not hating on APU's; it's just weird.
