I searched a bit, and found a few threads however i didn't want to crash them so apologies for going over a possibly well answered topic. However within the next couple of days i am planning on getting an imac G5 (17" or possibly 20" depending on my student discount!) Anyway i am currently a pc user and in my pc i have a couple of sticks of Twin Mos PC3200 DDR ram. Rather than blow another £50 upgrading my memory to 512MB, will i be able to use this memory in the imac? Thanks
