I've nearly completed a new build - all but the video card. Planning on waiting for Ampere.

I have an old PNY Verto 9400 GT (PCIe 2.0) card that I installed in the new machine. (Asus Crosshair VIII Hero w/ Ryzen 9 3900x) I just need the old GPU to finish out the build, ensure parts working well together and permit use of the system until my target GPU is released. Do you see any issues with doing so? I'm mostly worried about compatibility of PCIe 2.0 and 4.0 hardware.
