Not the best idea if you've only been dabbling. For one, dual boot is a pain, and desktop distros like Ubuntu come bundled with all kinds of dodgy FOSS that can leave you more open to malware than an updated Windows box. I wouldn't switch to Linux as a primary OS until you can at least configure a barebones distro from scratch (i.e. before installing X with a DE or WM) and know your way around permissions and the security options of the kernel.
Another big issue is Linux still suffers from a lack of software compared to Windows. A lot of the Windows software I know and love (eg. foobar2k) has no decent equivalent on Linux. Hell, the best mp3 players for Linux use ncurses. In general most Linux software with a graphical front-end is buggy and gimpy as fuck compared to just accessing apps via the CLI so while Linux can be far more efficient than Windows, it requires the user to know their way around the system more by the CLI than by graphical concepts such as "folders" and shit like that.
So in conclusion, if you like the Windows way of doing things (graphically) then it's honestly not worth switching to Linux because you'll get shafted on a lot of software that Windows users can take for granted. If you're interested in ultimate functionality then Linux is WAAAAAAAAY the fuck better but hey there's always VirtualBox you can install on Winblows and play around with Linux in that without running any risks.
