I'm looking at buying a 27" iMac in the summer (freelance graphic designer) which comes with 2x4GB RAM from the factory. The 16GB upgrade is an extra £160 when building on the Apple site. There is a total of 4 slots supporting 32GB, could I buy 2x8GB sticks from Crucial (£65) and add these in the two empty slots so there would be 24GB? I wasn't sure if the sticks all needed to be the same size.
