I used to have a powermac G5 dual 2.0ghz for web and graphic design work. I then needed portability to work with clients in their offices, so I got a 17" core 2 duo macbook pro I will soon be doing less of that so was wondering is it worth selling up again and moving back to the desk. If so which one? 2.6 quad, 3.0 quad or 3.0 8core, I have heard the 8 core isn't that much faster. What ever I do I will be getting a 30" monitor to give me more space to work.
