Sounds like a job for a USB trial run on a rainy weekend when you're not doing anything else.
Nvidia supply OEM drivers for the Debian family (Debian, Ubuntu, Mint), if not others, assuming the open-source drivers don't cut it for you. Microcode updates are released for both Intel and AMD.
You'll probably run into issues with some games. Things are getting better on Linux, slowly and steadily, but many games are written specifically for Windows with no Linux port available. Steam's store, for example, shows which games are SteamOS compatible, which usually means they'll run on Linux too.
For other games it's worth checking the Internet - e.g. www.protondb.com to see if anyone else has a particular game running under Linux. You're probably aware that there are programs that attempt to provide some layer of Windows behaviour that form part of the solution. Some of the solutions may or may not involve command line use.
