Hi,

I am currnently using the ASROCK FM2A78M-HD+ FM2+ motherboard, and has a a10-6800K CPU. If I want to set up dual graphics features, can you tell me all the versons of all the Raedon cards that are compatibie with that AGU for dual graphics (the AMD website only listed up to HD6670, but I think the HD7xxx would work too with the a10-6800K series as dual graphics? Would the new R7 250 work as dual graphics too for my CPU or it only works with the newer A10-7xx0 CPU?

If R7 would not work as dual graphics for A10-6800K, in terms of performance, would you recommend i set up dual graphics with the highest HD7000 card it would work with? Or purchase a R7 250 video card alone and disable the onboard GPU and only use the R7 video card? What would be a better performance?

If the dual graphics with HD7000 and a10-6800K 8670D GPU will outperform a single R7 250 video card, which higher version of the R7/R9 series would you recommend over the dual graphics set up?

I mostly play skyrim, diablo3, elderscroll online, not the most up to date 3D games.

oh last question, to use dual graphics, I heard I need two DDR3 1866MHz or higher frequency memory modules in dual channel. Is that true? Currently I only have two DDR3 1333mhz in dual channel, do I need to upgrade the memory chip to 1866 to run dual graphics?

Thanks,

Thanks. So for the 6670/7750 I found the HD 6670 1GB 128-Bit DDR3 (not DDR5) for PCI Express 2.1 x16 to be $30 and the HD 7750 1GB DDR5 for PCI Express 3.0 x16 to be $60 on ebay. I have a PCI Express 3.0 x16 slot. Would the performance gain from 6670 to 7750 be noticeable enough to warrant me to get the 7750 instead for double the price of $30 more? (I am on a limited budget) . I think the most 3D intensive game I play currentnly is skyrim and diablo3 and elder scrolls online and dragon age II and lord of the rings online. Other than that nothing really.
