I am currently running 2 monitors on my PC, but I would like to add a third that I had on hand. My computer has an AOD 790 GX/128M Motherboard, with quad-core AMD Phenom II CPU. I currently have a Nvidia NX8800GTX GPU installed, which has my 2 monitors connected to it. I have a graphics card that I could install, however it is an ATI X1300. I would be willing to connect my third monitor either through the motherboards embedded graphics, or through my ATI card. Is it possible to do either of these? I am worried about a driver issue since the 2 GPU's are different brands, and I am not sure it is possible to use embedded graphics at the same time as a card. If this is not possible, what would be the cheapest way to add a third monitor? Thanks!
