Hey everyone! I have a white 20" iMac core 2 duo and it has 2GB of RAM and I've been advised by numerous people to max it out. According to apple, the max amount of RAM is 3GB, but thanks to the folks at MacRumors for finding out that it's actually 3.33GB (2x2). Since RAM is so dirt cheap these days i'm going to upgrade it and i've read that OWC has a great reputation, so i've been looking there and i found these two almost identical sets of 2x2 GB RAM and I was wondering if you folks could lend me a helping hand and tell me which one to buy...or if you recommend any other type of RAM. http://eshop.macsales.com/item/Other World Computing/53IM2DDR4GBK/ OR http://eshop.macsales.com/item/Other World Computing/53C4DDR2P4GB/ Thanks!
