Let me say that after reading
this page I have chosen that memory
Well of course a memory manufacturer is going to say that.
The benchmarks on memory scaling with Skylake differs quite a bit depending on which site you trust the most. One area that isn't in dispute is if a person uses onboard graphics. Every site shows a healthy increase using faster RAM.
But since the discussion of RAM scaling can quickly turn into a he said, she said, chart sharing one-upmanship that I hate arguing about, I will say that even the websites that say faster RAM improves system performance dramatically, after DDR4 3200 the performance increases are very miniscule.
If you aren't even overclocking your CPU, you really don't need to shell out the premium for DDR4 3600 over DDR 3200. One thing you do want to do is make sure that RAM is on Asus's QVL list or certified by the memory manufacturer to work with your motherboard. If it's not on one of those, the RAM may or may not work correctly with your motherboard.
My motherboard has issues with 8 GB modules that are DDR4 3200 and higher. In fact, G Skill doesn't have any 8 GB modules DDR 3200 and higher that they certify to work correctly in motherboard.
