I have a A10-6800K with the integrated 8670D graphics. I can also get my hand on a radeon HD 7500 video card or a R7 250x videoe card .
Should I use dual graphics with my a10-6800K pairing with HD 7750? or turn off the internal 8670D and just use the R7-250x? what has higher performance?
And yes the a10-6800K can dual with HD7750, see this article confirming.

i also called AMD, they confirmed that yes the a10-6800K is able to dual with the radeon 7750 or 7730, even though it's not offical. I asked about dual graphic with HD 7770, the AMD rep said he wouldn't recommend it... I am not sure if that means it can't be done or that it could be but not recommended, since both 7750 and 7770 are same core just different specs.
Is it possible that I am able to dual graphics with HD 7770? if it is possible, is it possible that I would not gain any benefits from it, or that it might even bring the performance down from just using a 7770 instead of 7770 + 8670D?
And that makes me wonder... since the r7-250x is supposed to be a rebranded HD 7770, would I be able to dual the a10-6800K with the r7-250x? If I can, should I?
thanks!
