I would recommend a second SSD where you can play with Linux until you get the hang of it. A Debian based distro like Ubuntu or PopOS provides a perfect out-of-the-box experience and lets you start getting used to working in the terminal. Once you crack the basics you'll never want to go back to windows as a daily driver. I wouldn't use arch as my first foray into Linux personally.

Why dual boot initially? As many have pointed out gaming compatibility can be problematic. Proton has come a hell of a long way but sometimes you just want something to work and work well in your downtime without faff. Also, unfortunately ,a lot of productivity apps like the Adobe CC need windows. You can get them running on Linux.. just about.. but frankly it's a shit experience. Also, there are times when you'll still just need that dirty second OS to get something running quickly (and you don't have time to track through stack overflow for 3 hours in pursuit of exceptionally high IQ solutions, fun as it may be)..
