. I have 8 6600k with out videographic card. AMD recomends to install RADEON HD 6670 for Dual Grapfics. Can I install, for examle, HD 7850 or HD 6850 for Dual Grapfics? Another HD series videographic card?
No, Dual Graphics only works with specific combinations.
On the other hand, why not just forget about Dual Graphics and go with the most powerful single GPU your system can support ? This will give you much better performance than Dual Graphics.
