I've been playing a lot of games lately (WoW to be exact) and I'm itching for more power, so I've been toying with the idea of slipping two of my PCs 512 chips in there. They're both rated at DDR333, while my computer currently has two DDR400 chips in it. I know that on PCs, putting slower chips in won't hurt(damage) the computer, it'll just make it run at a lower clock speed (the memory, that is). Will the results be the same for the Mac? Thanks!
