Wondering about AMD Dual Graphics Compatibility?

So I recently built a PC with an AMD A10-6800K Processor. The box and many reviews say that the best performance comes with enabling AMD dual graphics, which I know how to do. However, the packaging states that the Radeon HD 6770 and 6450 are the only cards recommended. I wanted to get a Radeon HD 7790 - will I be able to do dual graphics with this? If not, I'll go ahead and buy the card, but it would be great if I could use the awesome integrated GPU I have. Thanks for any help! :D

    Most likely not. Even if you could, it would be a bad idea. Dual graphics performs poorly in general, and the bigger the performance gap between the graphics card and the integrated graphics, the worse it would get.
    Don't worry though, the 7790 on its own will do fine.
  2. As a definite "No" it will not work. Like Sakkura said the 7790 is a good mainstream card.
  3. As said above the 7790 will do just fine on it's own. If you want to go Crossfire you can do that with two 7790 as long as your motherboard has two PCI-E x16 slots.
  4. The AMD Radeon HD 7790 is Crossfire compatible only, since it has a Crossfire connector and a 6 Pin PCI-e connection.

    Thanks! Will definitely still buy though, I just wish I could use those graphics too :/
    Thanks anyway! :D
    In that case, is the 6670 the most powerful card I can buy for dual graphics?
