I want to replace Win10 on the desktop system I mostly use for gaming. It is an older system with an Nvidia GeForce 1050ti gpu in it, which from what I found, should not be a problem. I was thinking about going with Ubuntu since it is well supported. I was interested if anyone has any opinions about this. I am also going to try and dual boot it with the Win10 for now. I purchased a new SSD drive just for Linux.
SteamOS 3 is only available for Steam Deck at the moment (or other handhelds in the near future). There is no desktop version for it yet. SteamOS 1 is over a decade old and not usable anymore.
Good luck with Mint or Bazzite! Either should serve you well.
