I'd buy the new PC so that your own PC can actually be your own still and your work stuff can be relegated to that new PC.
There's plenty of really good reason to not mix work and pleasure on your main PC, your employer or school effectively taking ownership of your main, personal system being one big one.
Optionally, I'd also just start looking for new work if you work for a BYOD place.
Hopefully this trade war doesn't turn into an actual war....
