With dual channel you can get up to a pretty high speed, I am going to be getting 2x 6400mhz 32gb sticks, but I'm pretty sure that anything quad channel and above starts to be limited to 5400-5600 or so, or even lower. But if you're doing creative stuff, that might not be what you're worried about, and you may just want a bunch of 5200mhz sticks.
