Should I buy beefy RAM for AMD Ryzen?

[TechnoStyle]

I'm thinking about buying AMD Ryzen 5 1600 CPU. When the CPUs overclocked, they can performs better with speedy RAM for ex 3200 Mhz.
In my country Gskill Flare X 3200 Mhz RAM is selling with 245 $ price tag.
The cheapest 2400 Mhz dual ranked 2x8 GB RAM kit is Crucial Ballistix Sport BLS2C8G4D240FSA with 114 $ price tag.
If I buy Crucial, will my performance hugely affected negatively? If the difference is 3-5 FPS then no problem but? (You maybe know, Ryzen 7 performs much better with 3200 Mhz RAM when overclocked. But what about Ryzen 5 ?)

Howdy, Just built a 1700 @ 3.8 1.32v - G.Skill Flare X 8gb @ 3200mhz on a Asus X370 Prime Pro and let me just say it is solid as a rock now after getting rid of the Corsair Vengeance LPX 3000 that would only run @ 2400 on my board. My cinebench R15 score went up over 100 points and BF1 CPU/GPU graph is now one merged line, nothing is bottlenecking anything now. Paired with a Samsung 960 Pro this machine is ready to work and play!

I simply answer my question.
If you have GTX1060, RX480 or lower GPU, then you can buy 2133 Mhz RAM. It doesn't matter.
But if you have GTX1070 or above, higher speed RAMs should be better. (Especially for 1080Ti. Sometimes you can see huge FPS differences.)
