FM1 is a deadend platform, why not FM2 and the just released Trinity for desktops? It is almost similarly priced and the performance gains are impressive over Llano (unless there is a very attractive discount)
FM2 is also supposed to be supported at least up to the Excavator based APU so it is future proof according to recent AMD leaked slides. (Excavator should be released in 2014 or 2015 and will be the 3rd APU for the FM2 socket). That and FM2 processors use less power than those on the FM1 socket.
Basically go with the recently released FM2 over FM1 or AM3+
