I tried searching! Does anyone have and notice a difference having 6 or 8GB of ram vs the stock 4gb doing basic stuff? By basic stuff I mean email, iTunes, iPhoto, Aperture, Safari, etc, etc... I'm thinking about upgrading my iMac to 8GB eventually, I know its expensive so I'd do it one stick at a time. I'm just wondering if its worth it. Via iStat I'm seeing that I'm constantly running down to less than 500mbs of free ram, sometimes much lower and my system starts to bog down. I dont do any "heavy" stuff on my iMac but I do have lots of programs open at the same time. Yes, I could close them and save myself money on the ram. I know this. Thanks All! EDIT: Just realized in the title I put current gen...If I recall the is the only gen that supports 6 or 8gb of ram so my bad.
