I figured out the outdated software cannot really compare to freshly-coded software in terms of speed and efficiency...
My experience has often been the opposite. Freshly-coded software often seems to cash in on limitless amounts of CPU and RAM ressources and is often far from optimized.
A few weeks ago, I decided to mix a project in Logic 9 instead of 10. I was blown away by how efficient, how fast and smooth it was.
Likewise, I remember using Cubase VST a few years after they'd moved to the next generation of Cubase (SX). It was fantastic.
I'm guessing Sonar 8.5 on a relatively modern machine would be killer. That's a rig I've long been considering adding to my set up. And with Cakewalk dropping the idea of a Mac version, I'll probably go that route.
