Different GPUs in one PC. (lemmy.world)

So I recently upgraded every component in my PC to be fairly high end, except I didn't have the money to upgrade my GPU at the time so I was running with my old GTX 1070 for a while. Today I had some extra money so I finally got around to picking up a RTX 4070 super.

While installing it I just discovered a slight hitch in my plan. My primary monitor is 4k and uses display port so it isn't an issue. But my secondary monitor is an ancient 1080p monitor which only uses dvi and vga. The 4070 super only has display port and HDMI slots. I've been running with two monitors for so long that I don't know if I can stand going back to a single monitor.

It's already too late to run out and pick up an adapter so my plan for now is to install both GPUs in my PC and just pull the 1070 back out whenever I get around to getting a new secondary monitor or an adapter. Will a RTX 4070 super and a GTX 1070 both work in the same PC or am I just stuck with one monitor until I can get an adapter?

Depending on the type of DVI you can just buy a small DVI to HDMI adapter. I've run this setup for years when I got a gpu without DVI.

HDMI to DVI is normally a passive adapter, so also reversible. There are super cheap ones on Amazon.
For 1080p, any will do

They should work together. You are running Windows or Linux?

You’ll have to be careful to install compatible drivers that work for the two different GPU generations, but otherwise shouldn’t be too tough to manage.

You’ll just need to set which GPU is default for graphics applications.
