Should I buy a used Steam Deck for Forza Horizon 5 and potentially FH6?

I'm a recovering Xbox gamer who grew tired of the monthly cost for the ability to play my purchased games online. Purchased a pre-built gaming PC …

Forza 5 ran ok on my steam deck when I had it. I wasn’t getting super high fps or anything, but it was stable, good enough to make the road my bitch whenever I had a spare minute.
