Thank you to everyone’s support. I did not expect as much support as you all provided. I’m happy to announce a huge success! Ubuntu is installed, I’ve overcome several hurdles, and have a few more to go. I’ll try to post in next week to summarize my progress and challenges.

Something to note for the future, never install windows after Linux, even they are on different drives. Windows boot manager is very invasive, it likely will overwrite your Linux boot manager.

If you use Steam for gaming, then probably most games will work either directly or through a specific Proton version (you can set this in Steam). Games that won’t run are most 3rd-party launcher games and games that intentionally use ring 0 spyware.

In my opinion in modern computing I’d rather be on a “faster” releasing distro such as Fedora, Arch Linux. Modern hardware depends constant patches to the kernel to keep up with new sleep management changes and improvements to the GPU stack etc.

The biggest problem you’ll encounter with mint in particular is that multiple monitor support can be… hit or miss, other than that, gaming on Linux has been very good for a while now and it’s only getting better. Unless you are really into valorant or destiny 2, pretty much all of your games on steam, epic games and all other stores should just work. My personal recommendation is to try fedora, as I’ve had a much smoother experience with it…

I use debian for gaming and light LLM workloads and it’s been serving me quite well. Really like KDE.

Gaming is the only area where things might get tricky at all, every other area will pretty much just be a matter of getting used to different UIs.

Whether or not you find it sufficient for your gaming needs depends mostly on what types of games you play. If you’re always playing just the newest AAA titles, you might have some trouble, but there are a whole shitload of great titles that work perfectly on linux, and more are being added/ported every day.

As far as distro goes, I think Mint is a good choice for what you describe, you could also try one of the gaming specific distros, but my understanding is that those are generally overkill unless you’re making a gaming box

You wont know for sure until you try. the main sticking point for gaming on linux is anti-cheat, so if you play a lot of games with that then you may run into some trouble. otherwise ProtonDB is your friend. Most games these days are pretty easy to get up and running.

A lot of AI tools are developed on linux anyway so you shouldn’t encounter too many problems there.

Browsers are no problem at all. I recommend Firefox

Gaming on Linux is absolutely possible, but you have to have the right mindset for it. Put it in its own category. There are games that work on XBOX, there are games that work on PS4, there are Games that work on Windows, there are games that work on Linux. There is significant overlap between all of these, with many games working on all the platforms. Some games work better on some platforms than they do on others.

If you go at this with the mindset that you are going to play all your favorite Windows games on Linux, you will be as disappointied as if you got a PS5 to play Zelda and Animal Crossing. But if you instead go into it with the mindset “this is a gaming platform with thousands of games I can play on it, I’ll play the games that work on this platform” you will find that gaming on Linux is a perfectly adequate gaming platform.

My main needs are gaming

Most gaming needs, you’ll have to check protondb to see if you’d be comfortable not being able to play certain games. (games not on steam, you can look to Lutris for community made installers)
While Gold and Silver means games require slight setup (setup is usually explained by user-reports), Platinum means you’re good out of the box, Borked means no chance, you especially want to watch out if your game has an Anti-Cheat (and read the latest user-reports on the game if you’re truly desperate to see if things changed in the last week, like sometimes something like Gundam Evolution quietly enables the linux option in EasyAntiCheat)
If you have a steamaccount, you can log in to get the list of games that you already own on that account to easily see their ratings

Guides are straightforward, you just have to worry about whether you have nvidia or amd

browser stuff

no issues

Be careful when dual booting. I’ve had to manually rebuild my partition tables way too many times because Windows doesn’t like to play nice. That was dual booting from the same disk though so ymmv with a dedicated nvme.

you should be fine. gaming is dead simple with steam + proton

if you wanna torrent games, it’ll be a bit more involved but still doable

the AI stuff should work just fine, you just wanna make sure you go for a distro with good hardware support

I recommend to Install windows on its own drive. I had Windows one time do something to the EFI partition and I wasn’t able to boot linux after. I have heard of people having a separate EFI partitions for linux and windows to avoid this problem.

This is the way.

Unfortunately, if you don’t already know the answers it’s more a question of experience before you’ll understand them.

When I started with Ubuntu I couldn’t do dualboot, so it was hard. It got better with each update, but my beloved Gnome2 desktop was threatened and Ubuntu went on to Unity - KDE sucked, so I jumped over to Linux Mint with Cinnamon desktop.

Whilst it was great, I had terrible issues getting software - PPA’s are often suited to Ubuntu and not Mint… so in the end I tried installing Arch, failed twice, then got a Manjaro (Cinnamon) ISO and tried that for a few days, got some snapshots (rsync to my HDD) and then figured it’s not a big deal to install KDE, as it’s easy enough to go back.

KDE was so much better by then (about 5 years back) that I’m stuck with Manjaro KDE - having access to the AUR to install stuff is awesome, and flatpaks work at the flick of a settings switch too.

Dual-booting gives you the luxury of (if you wanna play Genshin Impact) having the option to boot into your game OS but also the ability to install games on your Linux OS and decide which one runs best on your hardware.

Everyone has such varied ‘needs’ that your question is impossible to answer - you must just suck it and see.
