Hi Bob,
I have a G5 dual that came out just before Apple went to Intel. I use it as an idea machine, as well as a DVD duplicator and VHS to DVD converter. I also conver LP's to cd's on it. I have GB on it and part of LogicPro. Some of the Logic stuff will not install on a G5, also cubase 4. For what I want, it is a very serviceable machine. My main computer is an iMac intel duo. So I am pretty good to go. Only wish I had waited 2 more months.
