Hello there,

I am going to buy my gaming pc soon but I don't know which kind of ram to buy.
I'm going to buy Corsair Vengeance Pro. But I can choose between:
-Corsair Vengeance Pro 1600MHz CL9 for €154,99
-Corsair Vengeance Pro 1866MHz CL9 for €168,99
-Corsair Vengeance Pro 2133MHz CL11 for €173,35
-Corsair Vengeance Pro 2400MHz CL11 for €174,30

Please answer!
Thank you :D

Oh yeah, I forgot to say that I'm planning on doing games and video editing/rendering, so do I need to buy one which has more MHz then?

So buy 1866? And I saw that in your PC specs that you chose the MSI Z87-G45 Gaming. I wanted to get that one too but then I saw the Asus Z87-A. Why did you choose the MSI Z87-G45 Gaming?
