Hi, So I'm running a new MP (2x2.66Ghz) with 2x512mb of ram. I'm looking at getting more ram, I don't want to spend too much, but with that said, I don't want my CS3 apps to be sluggish whilst listening to iTunes in Leopard when it arrives. So I'm assuming I can still use the 2 apple 512 sticks but what's this Quad memory channel support thing? And what would be the best configuration? Also, anyone know if there are any Australian stores that sell MP ram or any international stores that ship down under? Thanks guys.
