Two graphics cards conflicting
I just built a new machine from scratch using an ASRock AB350 Pro4 motherboard and a new video card, an EVGA GeForce 1080 SC. Since the 1080 has only one DVI connector, I decided to add my old card back in, an EVGA Geforce 9800 GTX+. I want to run my two monitors off the 9800 and use the 1080 to speed up rendering in Adobe Premiere and After Effects. The system ran fine initially with only the new 1080 card installed. The problem is that after I added the 9800 back in and plugged both monitors into it, the monitors ran fine for a few minutes, but then it seems like the 1080 hijacked things. Both monitors went black with no warning. The 1080 had taken control. I reinstalled the 9800 driver and both monitors worked fine when plugged into it, but then again, after just a few minutes, the 1080 took over and I had to plug a monitor back into it—nothing at all coming out of the 9800. How can I set the 9800 to be the feed for my two monitors and just use the 1080 for rendering?

EDIT: In fact, when I go into Display Settings->Display Adapter Properties, it doesn't even see the 9800. It just shows the 1080, as if the 9800 isn't even installed.

Both cards need to share the same driver (cannot install two differing Nvidia drivers on the same OS). Since the 9000 series was labeled EOL (End of Life) back in 2014 there is no driver which supports both units.

You can use a HDMI > DVI Adapter to connect a DVI device to a HDMI connector on the video card.
