Hi there, I'm currently using my two year old Macbook Pro 2,5 GHz Core 2 Duo with 4 GB DDR2 RAM for making music with Logic Pro. I want to upgrade to a new Mac because the CPU always reaches 100% in my projects. As a dance music producer I use a lot of vst-instruments and effects and do little recording of real instruments. I was thinking about buying a Mac Pro One 2.8GHz Quad-Core Intel Xeon W3530 “Nehalem” processor, but now the new Macbook Pro's have quad core processors as well. Therefore I'm considering buying a 15 inch Macbook Pro in stead of a Mac Pro. Does anyone know if there is much difference in performance between the Mac Pro and Macbook Pro when using Logic? Thanks!
