Your saying the A10 is more expensive, technically its not because you have the GPU already, subtract that 530 Card from the A10 pricing and it's actually the cheapest.
Theres little point buying the A10 and sticking that GFX Card in.
Option A or B are the better candidates in the setup your trying.
personally I've now owned an FX-4170,4100,6100,6200 and an 8150 and now I've sold all and gone for the A10-6800k , but that is only because the entire rig has been compressed into a Micro -ATX case to be a media centre. I have no intention of ever adding a GFX card to the set-up.
...So Far this little A10-6800k is performing admirably and I can't fault it, It does seem to run a little hot, but I'm looking at Underclocking it to reduce temperatures as buying decent cooling for this machines purpose seems pointless.
I'd Think for what your trying Option A: sounds the best.
However if your looking to upgrade the GFX card in the future, take the bomb proof 8320
