Geez I dunno, ... manners, manners, manners , these young folks, eh, Bill?
G'day and welcome to linux.org - I am an Aussie, from DownUnder, and 61.
(Wizard appears in a puff of smoke).
Linux caters to both ends of the scale, there are Distros (distributions) that are lightweight and can breathe new life into legacy equipment, and there are those that are like a champion racehorse that just want to get out and run on a rig such as yours.
The hardest part at the beginning is choosing a Distro, there are so many, and each has its merits.
A good site to make friends with is DistroWatch -
https://distrowatch.com/ ... and its Page Hit Ranking (see top right-hand side of its entry page). The most popular 50 - 100 distros are likely to have the best support.
DEs (desktop environments) are a bit like the difference in look and feel between Windows 7, 8 and 10, and some have specific apps and file managers that attach to them. For info on those

For Gaming, we have just started a new section here in the last few days, which I have no doubt will grow -
https://www.linux.org/forums/linux-gaming.202/
For general navigation around this site, up top-left, betwwen Home and Members,
right-click Forums and open in a fresh Tab and you can see where to best direct questions. But you are in the right spot here to fire away with any questions.
I run about 90 Distros (not a typo) on mainly 2 rigs, so will likely have some knowledge on whatever you choose to ask about, but there are many folks here, all volunteers, happy to help.
If you get the time, perhaps swing over to
https://www.linux.org/forums/member-introductions.141/ - and tell us a little of the Bill Massey story (and more about that Mandrake) and meet a few of The Gang
Thursday here in Oz, folks, so
