Craig -- I should hasten to add: The AMD A4-7300 64-bit dual-core CPU + GPU you were talking about is magnficient but is from AMD's higher-power-consumption 2014 'Kaveri' line of mobile-targeted SoCs that (as you say) fit in FM2 sockets. Kaveri is part of AMD's 'Steamroller' architecture, 2014 successor to 2013's 'Piledriver' (Trinity/Richland) SoCs, and is on 28nm dies. Kaveri appears to be the higher-power line in parallel to the lower-power 2014 'Puma' (Beema/Mullins) line I've been writing about along with the 2013 'Jaguar' (Kabini/Temash) one. Point is, a Kaveri-based system is high-performance indeed and no slouch even as a gamer box. But Kabini-based systems (even though it's an older and less powerful SoC line) is reported to be fast enough to be home-theatre PCs, and can be extremely cool / quiet and in some cases even fanless -- and sip tiny amount of mains power. I'm considering building a 32GB RAM 'Kabini'-based system on an ASROck mini-ITX motherboard to handle a variety of roles on my house's inside LAN. Because it's 2015 and because KVM virtualisation is a thing of much wonderment.
