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 …

FH6 is supposed to based on the same engine as the new Motorsport game. FH6s minimum system requirements are even more than Motorsport. And Motorsport runs like butts even on a higher end PC. 5 might be playable, but 6 almost definitely won’t be.
Dang I really liked the idea of the deck, but that’s another fair point about FH6 probably not running well.
