I'm going to be adding RAM to my iMac soon, and I was just wondering about something... Should I be upgrading to 2GB or RAM so that I can have matching pairs of 1GB sticks, or should I go all out for the 3GB? The price difference doesn't mean much if the performance boost will be significant enough. The only problem I see is the dual-channel thing. Is the boost from that enough to offset the extra Gb of RAM? In other words, will my system run FASTER with the 1Gb, or will it not make a big difference due to the fact that I'll be losing the dual-channel benefits? I use my computer mostly for listening to music, surfing the internet, email, making home movies and the occasional game. I may eventually end up using it for things like recording music and I am currently teaching myself how to use Photoshop, so my RAM needs will PROBABLY be growing. I'm just wondering what you guys suggest, especially with Leopard coming and all. Thanks a lot!
