I currently have a 13" MacBookPro but am looking to upgrade to a higher spec mac. I play games on my computer and need a more powerful computer to support certain games. I also use video editing software to edit gameplay I record from my xbox 360. I will also probably be using boot camp to install windows to run windows only games and programs Basically I want to know whether or not to get a iMac or Mac Pro .. and which specs would be best to get on them? Also I have been looking at USB 3.0 and wondering if I bought either of these will I have to get a whole new computer to support it or just a PCI card upgrade.... same with lightpeak. Sorry if theres any stupid mistakes/things in there as I know a bit about computers but not enough.
