When I started building a computer and realized these new cards were going to be unobtainium last fall, I bought a used 1080ti instead. Despite being older it still holds its own against newer cards. Lacking RT and DLSS features (which didn't matter much to me), it was reselling at a sizeable discount vs comparable used 20x0 cards.

Five months later I still have my eBay searches saved, and the exact model I bought is now regularly selling for 40+% more than it cost me. There's one right now with a few hours left on the clock, currently going for 50% more than I paid, with 75 watchers and 51 bids. It's wild.
