Agreed! The Nehalem MacPro's are very powerful machines that can handle high track counts with lots of plugins. With that said, I run a 2008, 8 core Harpertown and have had nothing but great results with that machine. From what I've read, lots of guys on this forum are using the 2008 model and have yet to max out their full potential. Obviously, a newer, Westmere Mac Pro will be relevant for longer but there's also the additional cost to consider beyond a used 2008 or 2009 model.
