Used 2080 or Used 3070?

Hey My previous gpu has died like 2 months ago and I have l have returned it back to the service and they are about to pay back the price of it, so I'm planning to switch to a nVidia gpu after I had RX 5700 almost 3 years. I'm looking for a used card, because that's way more cheaper than a new one, but the only thing that I can not decide is, which series is more worthy nowadays? Thanks for the help in anticipation!

Edit: I have 2 1080p screens and most of the times I'm playing Valorant, lol, CS:GO, LEGO games and Yakuza series. I'm trying to decrease my time spent on my pc to have time for more important things in life. 😅

I've just found a 3080 for a good price. It's about 370 EUR. 👀
