Why suggest a FX processor over an APU? What about dual graphics?

I don't really understand the technology but why do people suggest FX + Discrete Graphics card instead of an APU (Like the latest A10) + Discretre Graphics card.

Why not like a A10+ 290 instead of a FX + 290.

Doesn't dual graphics bring in more graphics potential? The power of two?

this ain't amd the only official gpu that amd release for dual graphics with a10 (kaveri) is r7 240/250 with a series richland are hd 6570 and hd 6670

the dual graphics i can think of for r9 290 is amd xfire

because the fx processing power is stronger than the a10

if you have a dedicated graphics then there is no point getting an apu because the integrated graphics will only be a waste

you can't dual graphics an a10 to a r9 290

you can only do dual graphics with r7 250 (a10 7850k + r7 240/250) which can only run bf4 on medium 40FPS

all in all FX+290 is way better (especially if it is octacore) than a10+290

Using the APU's GPU for gaming along with a strong GPU doesn't work very well due to how multi-gpu rendering works. If AMD allowed it your rendering speed would be a bit slower than double the APU's GPU speed. As the 290 would be waiting on the APU to finish each of it's rendered scenes or section of a scene. (Most Multi-GPU rendering either works by splitting a scene or alternately drawing scenes one after another hence why you would want GPU's of equivalent or nearly equivalent speeds).

Now given that an APU's GPU could be used for compute purposes, but as of now no current games use the compute capabilities of GPU's in such a way where Intel and/or AMD onboard GPU's would be useful for gaming. Hopefully as HSA capable CPU's become more common we will see them used more especially for gaming purposes.

Then why does the 290 advertise dual graphics? I don't understand. Why advertise that it does if it doesn't?

"Get the power of two when you purchase an AMD A-Series Accelerated Processor (APU) based PC with an AMD Radeon™ DirectX® 11.2-capable discrete graphics card. Only AMD Radeon™ Dual Graphics combines two powerful Radeon™ DirectX 11.2-enabled graphics processors to provide the ultimate gaming performance boost when you need it. - See more at: http://xfxforce.com/en-us/products/amd-radeon-r9-series/amd-radeon-r9-290-black-double-dissipation-edition-r9-290a-edbd#sthash.x9ZEKSEz.dpuf"
