I've seen several posts related to music production on a Mac, yet I still am having some issues resolving my situation. I'm currently running a 2 GHz Macbook with 1 GB of ram. I use the computer for school, and have recently decided to dive into electronic music after years of acoustic performance. I'm interesting in running Ableton Live Suite, and I'm wondering if buying a secondary Macbook is worth the investment. I am a student, so money is an issue. If I buy another computer, it would likely be a 2.4 GHz Macbook with 4 GB of ram. Is that extra processing speed going to pay off, or should I just upgrade the machine I have now? I realize I'll need an external firewire audio interface, but right now I'm just concerned about processing capabilities... Thank you to anyone that can offer advice.
