I built it literally as the gtx 1080 was being released. It was a beast when it was new. 

I still have it in its box, a hell of a processor for the time, well- until it got hit by Intel’s mitigations for Spectre and Meltdown. It still has value, someone wanted to buy it from me for 80 bucks

Oddly enough, it's older, but still pretty decent. I built it myself and it was pretty cutting edge at the time. Apparently they don't support my Intel Core i7-6700K 8M Skylake Quad-Core 4.0 GHz which I actually found a bit surprising.

Switch to linux?

I switched indirectly -- switched from Windows to Mac, then to Linux (and still use Mac when I'm at work). 

That said, if your main use for a computer is writing and using the internet (I'm guessing a machine old enough to not be eligible for the upgrade probably isn't creating videos), Linux will be just fine. There are plenty of builds/interfaces that are great for newer users, and LibreOffice can do everything I ever used MS Office for.  Just remember you are changing user interfaces, so there will be a learning curve.
