New guy here 
If I get a IMac 27 5k Retina with 16 GB of SDRAM (2x8GB )
Where do I get the other 2x8GB of SDRAM to make it 32GB ?
Or do I fork out the $400 and go for 32 GB when I buy the machine ?
Seems a bit ridiculous to pay that much don't talk think
I'm quessing I need a total of 4 x 8Gb cards to maker a 32GB system.
I'm smart like that kinda sorta.
Thanks in advance
