Hey guys so basically here's my dilemma. I currently have about $1000-1700 for a Mac Pro ($1700 being about the absolute max). Now I'm a music producer and I use a lot of 3rd party plugins and instruments with Logic 9 and average about 30-60 tracks per song. I'm currently using a late 2010 Macbook Pro dual core with 8 gigs of ram, and it is a nightmare. Logic gives me the overload message all the time, to the point where my workflow is horribly slow from having to bounce/freeze tracks. So I'm getting a Mac Pro to combat this issue. So I think Logic uses about 8 cores max at the moment? So I want to ideally get an 8 core system. The price difference between a late 2008 Harpertown Mac Pro and an early 2009 Nehalem Mac Pro is fairly large so I want to know if there is a huge difference in performance/relevance between the two when it comes to Logic Pro and music production since this is all I will be using it for? Also will the quadcore Nehalem really give me the same processing power as a Harpertown 8 core? WOuld it be cheaper for me to buy a dual slot quadcore and upgrade it to an 8? Thanks guys!
