Hey everyone, My fiancee owns one of the "new" 24" iMacs and absolutely loves it. It's a 2.8 GHz with 2GB of RAM, and she's starting to have trouble with command delays. She's a photographer and spends most of her time editing massive pictures in Photoshop CS3. She likes to listen to music, check her previews, and everything else all at the same time. Thus, she's having some issues. I've been considering upping her to 4GB of RAM (or 3GB, depending on how much it costs), but I don't know exactly what to buy. I searched the forums and, due to my impatience, didn't find anything. Could someone just point me to which brands to look at? I'm supposed to get 200-pin 667MHz DDR2 PC5300, right? Thanks for any help!
