Indeed, I've had the same basic setup for a number of years, and this
month was the first time I noticed any slowdown in the rest of my
system while doing audio, and only now because I was working on a
session with a number of tracks and plugins far beyond most stuff I've
worked on before. The quadcore has been good to me for a long time.
