Thinking of buying a GPU

I’m guessing this is the best subreddit to ask this. I’m thinking of buying an RTX 3060 or RX 6600XT this summer. I will be buying them used and not new.

I was wondering how much would they cost used if the market wast screwed up? Do you think the prices will decrease more this summer?

I have a 1080p monitor and i wont be switching to 1440p.

Thank you!
