I have eight gigs of ram.
Why would you do something like that.
Adobe Premier 4 only takes 2. Real time video editing is one of the most memory taxing things I can think of, and unlike a processor, if you're not using 100% of your RAM, then the rest is just not used at all. If you buy 8 but you only ever use 2, then you just bought 6 too many gigs of RAM.
