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?

    For the most part, yes, you can do that. Assuming you have the PCIe slots and your PSU can power everything, that is.

    You might run into some weird issues if you try to run a program on one GPU and move it to the other’s monitor, or run something across both monitors, or try to use some kind of super-resolution monitor-spanning setup.

    If you also have “onboard” graphics (really CPU graphics now) and a motherboard DVI or VGA port, you might have better luck using that plus the GPU. Generally that’s better-supported, though you may need to check your BIOS to see if it requires specific settings.

      Thank you. I do have enough physical PCIE slots but I’m assuming its going to drop both of them down to x8 instead of x16. My PSU is a 1kw titanium rated one and I’m not going to be stressing to 1070 at all so it should be fine there. Unfortunately no onboard graphics because that would have made things easy. I’m not plannying on doing any fancy graphics setup and I’ll avoid bouncing windows between the screens until I remove the 1070. So here’s hoping it works for now.
