A10-6800k or A8-6600k

Solution
If they overclock, a single 270X will probably be OK but I agree that crossfire is a waste of a card because one of them will barely be doing anything.

An x4 750K/760K is basically an A10-5700 without the GPU part OP. There is absolutely no point getting an A10 or A6 if you are buying a separate graphics card, especially one as powerful as a 270 or 270X


a8 at around $100 while a10 at around $140.

I'm more after Performance vs price ratio because i'm seeing stuff like: "a10-6800k performs no more than 10% better than a8-6600k".

I do play games but not exactly into ULTRA settings. Medium to high settings is more than enough for me. Also planning to buy 2x R7-270 GPU's for crossfire
 
If you are buying a separate GPU DO NOT get the A10, do not get an APU at all!

The performance of the processor bit on an APU is pretty weak in comparison to other options like an FX 6300 with a socket 970 motherboard or even an i3 with a H81 motherboard.

I see APU's as a good choice if you really cannot afford a separate graphics card or if a graphics card will be a bad thing like in a low-profile home theatre PC. If you're building a gaming machine a strong processor is the way to go.
 


Problem is, my board is a FM2 socket (F2A55M-DS2). And i don't plan on buying a new Mobo, so just gonna max out what my Mobo can do for me.
