I have the mid-2010 3.2GHz i3 27" iMac. I'm sure you guys know this, but it comes with two 2GB sticks with two empty slots. I don't know much about this stuff. I can get Apple/Hynix factory original for $7.00 or Apple/Samsung factory original for $8.00. Or is there something else I should get? I can afford to to spend more money if need be. What would you guys do as far as upgrading RAM? Two more 2GB sticks like I was looking at or maybe four 4GB sticks? Right now, I don't do heavy computing, but it does bog down at times when I have a bunch of windows & tabs open. I also plan on doing some light video editing. Any recommendations? Any help would be greatly appreciated.
