SteamOS is mainly for the Steam Deck not regular PC or laptop. For a gaming distro I would recommend one of PopOS, Manjaro or Garuda.
I suggest grabbing the live image for each of them, booting it, and seeing how it feels without committing to anything. I usually test to see if everything works out of the box on the live mode — music, video, network shares, wifi, any peripherals you might have like headphones, fancy mouse or keyboard etc.
