Hey all ... I just got my first Mac ... after weeks of waiting my order arrived today. This is the first Apple that I've owned so are there any pointers that you all don't mind sharing. Sorry I don't know what to ask. I spent about at $6300 on this system and it's the most money I've ever spent on a computer. Here are the specs: - Dual 2.5Ghz - 1 GB RAM - 9800XT - Blue Tooth Keyboard & Mouse - 23" Cinema HD Display I have 1GB of RAM installed ... where should I buy RAM from? I need more for Video Editing with Final Cut Pro, DVD Studio Pro 3 and Motion!! Thanks!
