Oh absolutely! For years I put off upgrading because my old CPU was EoL and I'd need to switch out the cpu/mobo/ram and that just seemed like a huge pain. So I didn't do anything and suffered due to how slow and antiquated my system had become.

I finally upgraded this year and the difference is like going from a 1995 Hyundai Accent to a Bugatti Veyron, it's allowed me to work on the bigger scenes that were impossible to work on before and unlike my old system, I can actually still use my computer when I'm rendering those large scenes!
