What do you think of upgrading the ram in a late 2006 iMac Core 2 Duo? It currently has 1GB. Playing a 720p h264 video with 6 Firefox tabs only uses like 35% CPU usage, but eats over 900mb of ram. A lot of time's things can go sluggish and the beach ball of death appears! I believe these iMac's could only use 3GB of ram. This is also related to my Lion topic because I would like to upgrade if more ram helps. On PC's I found was 4gb plenty for anything, even gaming. Certain triple A titles used 6gb+ but it's not like this Mac can even play those. This is more related to a smooth computing experience overall.
