http://www.amazon.com/APPLE-iMAC-Al...1?ie=UTF8&s=electronics&qid=1229146195&sr=1-1 I was planning on trying 8GB of Ram in my girlfriend's iMac once it comes in. Now I know it will work. If it is for sale on Amazon, it must be working well. This is BIG. 8GB of Ram is a decent amount of memory. I once loaded every application I had on my mac pro and could not get it over 9GB of memory. Perhaps if I loaded a lot of big graphic images I could have gotten it higher, but it is unlikely I'd get it much above the 16 GB of RAM in there. I came to the conclusion that a reasonably fast iMac or MacBook Pro with 8GB would be a sweet combination that would support video editing well. So here is is, and I applaud it! Good for the guys at Techno Intelligencd for putting it together. Now as for me. I can do it much cheaper. I'll do it myself.
