the next 2 generation of AMD APUs are set in the same sockets. He can also overclock for about 10% more performance without needing to spend more money. All it comes down to is if he cares more about power consumption or overclocking. Neither of which is extremely significant.
This I will believe when I see it mainly because it depends on the cahges to the CPU/GPU core. There is no 100% gurantee that the board anyone buys today for FM2/1155/AM3+ will support the next CPU, even if they use the same pin count.
SO for the purposes of the OP, the only guranteed upgrade he can get is on 1155 if he ever wants to go to a quad core. Since we have very sparse information on the next CPU beyond Trinity (which can change, i.e. BD which changed a lot fro the original idea) we don't have that same 100%.

pentium is running as high as you can make it run and so is the A10. I don't see how the difference in clock speed matter in a comparison of performance.
This is true but again it shows the cores efficiency. Of course that is already know, Intels arch is much more efficient per core than AMDs.
Of course its also interesting how that was the major A64 platform, lower clock speed and lower power consumption meant a better CPU.
As for the "higher clock speed doesn't always mean higher power consumption, it normally does:
Idle its great, just like most modern CPUs. But under load:
And compared to the older Llano APUs, it uses the same but I assume its mostly due to the change from VLIW5 to VLIW4, less SUs but same or better performance. I would also assume some of it is CPU, probably some tweakes to the arch from PD but I haven't seen a test where they disable the IGP and test just the CPUs power consumption vs Llano.
