I did it. For a few years now I've wanted to make the jump but lazyness and a bit of worry that my main game wouldn't work very well kept me from it.
Then some effing windows update caused ridiculous stuttering on games (or maybe it was a auto-update of some other hidden thing, I couldn't figure it out) so I decided that if I needed a system wipe, might as well as try gaming on linux.
Honestly? Much easier than I expected. Install Steam, turn two options on and 90% of your library is ready to go. I had to tinker with getting freesync to work (ended up just switching to wayland, which just worked) but other than the plugins I use for my main game requiring a bit of more work, smooth as butter really.
So yeah, if you are a lazy gamer like I am, next time you do a system wipe or get a new computer, try installing linux first. Don't even bother Dual booting it, if you don't like it just reinstall (setup your usb drive with ventoy and the images you want to try out.)
You've basically described my situation exactly. I built a PC 6 months ago for Linux. I distro-hopped for a good while and settled on OpenSUSE Tumbleweed. Now I've put OpenSUSE on my laptop too. I would highly recommend it.
I went for an AMD GPU and have never had any problems with it. Linux is not as painless as Lemmy would have you believe though. Be prepared to learn some hard lessons and keep your data physically disconnected from the PC while you do it.
You've asked about WiFi drivers further down....on my PC, the only distros that had the correct WiFi drivers out of the box were EndeavourOS and ZorinOS. The rest all needed wired LAN to get them going.
