    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?

    The 27-inch iMac has a RAM door at the back that you can access after unplugging the power supply (there is a button hidden at the power supply plug), and yes you will save a lot by buying third party. In fact, you can get 4x8GB DDR3 for cheaper than what Apple is charging for 2x8GB. Make sure that you buy SO-DIMMs for laptops.

    The new iMacs use 1867MHz LPDDR3 onboard memory
