Hi,

 

I know this board uses HD integrated chipset and I have Nvidia 970. I would like to link those two to add more GPU power. Is that possible? (am on win7 8gb ram) thanks

I am not sure what you want to do, but it sounds like you are asking if you can set up a Crossfire type configuration using your integrated video on the mainboard with a separate video card. IF that is your inquiry, the answer in short is no. I can launch into a detailed explanation of why this won't work, but the end result will still be, "no".

Hi,

 

I seem to be eluded by advertising campaigns that it was possible to link onboard GPU with dedicated GPU. Is that another lie? Has no one done it?

AFAIK it's only on very specific hardware combinations designed to work together. For example, an AMD A10-7870K APU can work with an R7-250 graphics card in dual graphics mode. 

 

For info only - none of this is relevant to an Intel CPU - http://www.cpu-world.com/info/AMD/Recommended_graphics_cards_for_AMD_dual-graphics.html

 

FYI any of those AMD dual graphics combinations would be easily outperformed by a single GTX 970.

 

As an aside some laptops are configured to use the integrated Intel HD graphics most of the time, and only switch to the dedicated GPU when need requires (e.g. running a 3D game).  This is done to save power  and increase battery life.  I'm not aware of this being possible on a desktop PC.

If you had windows 10, you might be able too. The way this works is that the GPU renders most of each frame but the integrated graphics helps a little. The difference wouldn't be a ton but it would help.
