No more headaches
I purchased this from Mark Stein with the 16 gig memory upgrade. The device can handle Pro Tools 9 without breaking a sweat and also is perfect for Adobe Design programs. I can stack Virtual instrument tracks at a low buffer and do not have to bounce so I can record live vocals and guitars.
Also I've always enjoyed the design of the computer and Apples OSX workflow. I use to build my own Windows machines and go through headaches with Pro Tools. Save yourself the headaches and purchase a mac and get to work.
Mark's advice is always spot on
