    Now, I've noticed that Apple are being sneaky, because if you choose only 2GBs of RAM it comes as a pair (2x1GHz). Now if I wanted to buy some after market RAM and boost it up to 4GB, would I have to replace the whole lot or could I get away with buying a 3GB stick and leave one 1GB stick in there? I'm not sure whether the iMac uses matched pairs or not - would having a 3GB plus 1GB set-up be slower than a 2x2GB set-up?

    You either replace one of the 1GB sticks with a 2GB stick or do both. I have 3GB total installed and it's plenty fast even when running WinXP in a VM Fusion session with 1GB allocated to it...
