Of course I am not thinking I am going to play cyber punk 2077 60fps on steam deck with gorgeous visuals. I am mostly thinking of indie or very replayable games that I want to play on the go. For example no man sky is playing ok on switch but has a lot of bugs and crashes. On steam desk is the same as pc with low graphics settings which still looks good for me.
It is a whole another story for buying another monitor as I still yet to find the perfect monitor for me. I want to get a good enough looking ultra wide as I want to use it for work too.
