It’s pretty easy, I installed Mint on my laptop and the installer took care of the partition and everything. On my desktop, I just installed an m.2 expansion slot.
I was in the same boat but Linux Mint just literally worked. Easiest transition ever. I keep my Windows dual boot because I need MS Office for work but I’m in mint 95% of the time with no tinkering.
Glad it worked well for you. Didn’t work well for me with my 2070 super. Was immediately broken and refused to acknowledge my second monitor. Linux Mint worked perfectly, so I just want to throw that out there for anyone with the same gpu
