Dirt Cheap GPU Request - Crosspost with Gaming - Whack if not allowed

I'm putting together my first build and am (along with the rest of the world) waiting on an RTX 3080. In the interim, I'm trying to get my hands on the cheapest GPU I can find that 1. Actually works and 2. Has at least Display Port 1.2 or better so I'm not fumbling with adapters to get it hooked up to a modern display. Not to actually game, or even do much of anything, but literally to just be able to finish the build, boot into UEFI and then Windows for setup, confirm all of my other components work before we get too far from their purchase date, etc.

I found a few on Facebook Marketplace for $40 or so, but they were actually decent, albeit very old, cards, which is more than I need, and more than I'd like to pay for something I'm literally only going to use to get the rig set up.

So, if someone has a potato they have sitting in a shoebox in the closet that they are willing to part with for a few bucks and a song, let me know. Username at the google mail. Though definitely also post here, because I'm not exactly diligent at checking that throwaway account
