I know the obvious answer might be "yes" - but hear me out. I have a 2.8 GHz Octo Mac Pro with 4 GB factory RAM, 8800GT. I use my computer for mostly small tasks - Office, iWork, Internet, email, and gaming under Vista (okay don't get on me about why I have a MP for doing these things please). Would adding more RAM make a noticeable difference for me, considering what I use the computer for? I am thinking about adding more RAM but not unless I will notice an improvement. And how would things improve? Would applications start faster? Or would they actually run faster?
