I have to say half a year ago I finally upgraded my over 10 year old home studio PC.
It was still working fine using Reaper, Addictive Drums / Keys and a lot of other music software.
I don't have dozens of tracks and/or very demanding plugins running though.
BTW: I can recommend Reaper as a DAW, I have been using it for over a decade.
Cheap, stable, light on resources, a very active community, great stock plugins (although they look simple).
And there are great video tutorials over at Reaper Mania:
