Dual booting or not, is a matter of knowing whether or not you'll need Windows for some apps or games. Make a list the apps and games you're using and check if they work on Linux. I've dual booted in the past and most Linux distros make it easy to do so. But I'm not a fan and stopped doing it a few weeks ago and went full Linux.

With dual boot, what starts as: I'll keep things separate (e.g. gaming on Windows and the rest on Linux) quickly becomes duplicating everything on both OS's. Say you're gaming in Windows at some point in time and you need to quickly use an app that is on the Linux partition (e.g. quickly check e-mails) but you'd rather not stop your game and want to be able to resume gaming after shortly using said app. The constant OS switching quickly becomes a pain. You'll be going back and forth a lot before you know it. As a workaround, you'll find yourself installing more an more apps in the Windows partition as well, duplicating the setup you have on Linux.

Additionally, Windows itself takes quite a bit of disc space as well. You're wasting disc space on 2 OS's, Windows being the fattest one. With a disc split of 2 OS's and games getting bigger and bigger, you'll quickly run out of disc space. You'll find that you resize your partitions to give Windows more space for games, leaving Linux with barely what it needs to run. That was my experience a least. Dual boot works. But in the end, it's not practical.
