Build Advice How is this PC Upgrade?

[epicitemhd7]

Ryzen 5 1600 -> Ryzen 5 3600
Arctic Freezer 34 CPU Cooler
GA-AB350M-D3H
Antec GX500 Window Case
120GB SSD
1TB HDD
GTX 1070TI Strix
Antec neo eco modular 550w +Bronze
Crucial 8GB 2400HZ RAM
ADATA 8GB 2666HZ RAM (Mobo underclocking it to 2400mhz I guess)
I guess having 2 different ram sticks makes my PC underperform badly so I'm upgrading it to 2 options :
GSKILL Ripjaws 3200MHZ 2X8GB
or
Corsair Veageance 3200MHZ 2X8GB or 3600MHZ but my mobo won't support it I guess.

How will this PC work and which ram sticks are better?
I need a pc to play 1080p 144fps on most competetive games (R6S,Apex legends,PUBG,etc...) on lowest settings usually but medium is good too ^^

Should I upgrade my MOBO for better cooparation with the CPU and RAM or is it good ?

I asked how my build will work, and to which ram of 2 options should I upgrade to.
