I had very few issues with a GTX 970 and i7-4790k. The only issues I hear about with either any more is the linux kernel not supporting some of the features of newer GPUs (e.g. I know ray-tracing was a pain-point at one point).

I don't like recommending distros based on such a general use case, mainly because every distro can be tweaked and configured to exactly what you want. Instead, you should research the different mainline distros that have been around for decades—Arch, Debian, Fedora, Gentoo, Guix, NixOS, OpenSuse, Slackware—and see what they're about, what sets them apart from others, what the maintainers' philosophies are, and what kind of package management system they work with. Once one sounds better than the others, look into it and try it out.

#Dos and Don'ts:

Don't try a niche distro. They are harder to troubleshoot and less likely to be actively maintained.

Don't use Ubuntu. It's just a suckier version of Debian. It used to be user-friendly Debian, but now Debian is more user-friendly than it.

Don't dual-boot with windows. This just solidifies your reliance on windows, especially if you're the type to give up on problem-solving issues that you didn't have in Windows. It also can cause issues with making Linux unbootable.

Do try a live usb with persistence before you commit entirely. It's not exactly the same as a complete install, but it's close enough to let you know how the OS feels and what hardware will or won't work with it. Some people say try a VM first, but that won't have direct hardware access.

Do problem solve the little things. Anything that irks you or bothers you or just slows down your workflow. It doesn't have to be an actual bug or glitch, just anything that could be better. This not only solidifies the feeling of ownership over your OS—you no longer have to settle for anyone else's lousy design choices—it teaches you the resources for troubleshooting larger issues.

Do plan around things not being plug and play at first. Want to test if a game runs on Linux? Great, set aside a couple of hours beforehand: first to install steam and set it up, then to figure out Proton, then to troubleshoot the game not even booting up, then to fix any glitches or whatnot, then to get your controller working. This won't always be the case, but it will irk you a lot less when it is if you expect it. The more you make time for solving these issues now, the less time they'll take up in the future (either they'll be gone, or you'll immediately know how to fix them, or your troubleshooting will be more streamlined).

Do set aside time to learn about Linux "under the hood." You don't have to become a computer scientist, but it will save you a lot of headaches, show you cool things you can do, and make your computer a smoother experience. It especially helps if you take the time to learn as they come up: e.g. installer asks you what "bootloader" you want, but you're not sure what that is, what it does, or why it's necessary? Now's the best time to take a little learning detour.

Do ask questions on forums.

Don't listen to the people who shame you for asking.

Do listen to the people who try to show you a better way of doing things, even if it's not your way.
