How many gigs of RAM do you have?

16. One thing that matters and is often overlooked is the type of memory (DDR4 or DDR3) and the speed (2133 MHz all the way to 4800 MHz in the case of DDR4). Also, dual channel is really important for additional performance (look it up if you want to know what it is).
My RAM is corsair 2x8 GB Corsair Vengeance 3600 MHz RGB (lol). 16 GB is probably all you need for gaming.
