I'm going to max out the processor and graphics card on a new 27-incher, though I figure I can save money buying RAM 3rd party. 1. I know nothing about RAM. Can I use sticks of 8GB DDR3L - 1600 in the new iMac? 2. I'm likely going to want a total of 32GB of RAM though I might want to go for more at some point. Based on this, how is it best to configure the RAM in the Mac to make it easy to upgrade? 2 sticks of 8GB from Apple? 3. Will I save much by buying the RAM from a 3rd party OR is it not worth the trouble? Thanks!!!!
