I'll contribute my two cents.>Is Linux pretty good? Also what would be a good distro?
As previously stated, this depends entirely on your situation.
In general, Linux is more compact and lightweight than Windows, leaving memory and CPU cycles free for other tasks.
For someone new to Linux coming from a Windows background, I would suggest Ubuntu or Linux Mint. They're designed to be comfortable for people who are used to Windows, though they feel much more like Windows 7 than Windows 10.>I'm not very familiar with it, but I wouldn't be opposed to switching if I can get it to run Windows apps.
This depends on exactly which apps you mean. Linux Mint I know come preinstalled with a variety of open source variants of proprietary Windows and Apple software that can even read those proprietary formats.
Libre Office suite = MS Office Suite and can read and write MS Office file types. These programs due lack proprietary MS fonts, but they include serviceable alternatives.
GNU Image Manipulation Program (GIMP) = Photoshop. I was never an advanced Photoshop user, but for my purposes I've never been able to find anything that I could do in Photoshop and not GIMP. You can even download scripts and plugins that'll do things that GIMP can't originally do out of the box.
Steam runs fine on Linux, though it depends on exactly which games you'll be playing. For example, my wife likes The Sims, but even though she owns the game through Steam, it still has to run through Origin because EA. And there is no way to get Origin to run on Linux, nor is there any way to bypass running through Origin. I spent days on this problem. So some games will run fine on Linux, like most of my library. Some games will run through compatibility programs like WINE, and some will be impossible to run.>I'd contribute wallpapers or make OC, but I'm not really sure what to make.
It's cool, dude.
