I just ordered a 20" Imac Core 2 Duo with 1 gig of ram (2x512). I was just wondering what ram was the best type of ram to get for it? Also, would it make sense for me to have 1 gig, and 2x512 stick of ram in it? I was thinking of putting another gig into it and just needed some help on it. Also does anyone know any good websites to order ram off of? Thanks for the help.
