To start, I've only used PC's. For the most part, my computer usage was pretty basic, which didn't require the machine to do much - surf the internet, type documents, etc. Very simple stuff. However, I am now jumping into advanced video editing - the kind used for music videos and I need a machine that can handle that. My band's first music video was edited on a PC, and while it turned out good, it was SO UNBELIABLY frustrating attempting edit HD video on a PC. So here I am, looking at potential macs, and I am looking for advice on what to purchase. I know I am going to need at least 4 GB of RAM - will upgrade to 8 GB if possible. I will be editing full HD video clips (1980x1020), as we are shooting with the Canon 5d and 7d. Since I am only using the mac for video editing purposes, I am really looking to find the most bang for you buck I can with a new computer. Hard drive space will not be that big of a deal - I will be editing the files mostly off an external hard drive. And while I would love to have a large monitor for viewing, that's also not high up on my priority list. I just need something to get off the ground with but that's also reasonably priced. I can upgrade the monitor later. Price range Im looking at is $600-$1000. I appreciate the help.
