then who is an APU meant for ?
People who don't want to buy a graphics card or would have run something like a 6450 or 6570 in the past.
If you add anything higher than a 6570, then you pretty much just paid an extra $25 for an FX-4300 as you won't be using the graphics processing portion of the CPU. A10 is essentially an FX-4300 with a 6570 built in.
