If You go for 2133MHz memory's then to be able to have them at that speed, You must activate the inbuilt Intel® Extreme Memory Profile (Intel® XMP)
in the Bios Setup, otherwise they will only run at 1600MHz..
look into your motherboard manual how activate memory XMP
Another important thing to remember: activating the Intel XMP will slightly overclock the CPU as per automatic.
I'm running similar memory's myself:
Motherboard: Asus Z97 Deluxe
CPU: Intel Core i7 4790K @4.6GHz
Memory: 16GB (2x8GB) 2133MHz Cl11 G-Skill
Monitor: 2x BenQ 24" 1920x1080
Graphic: ASUS Radeon R9 290 4GB
C: SSD: Intel 520 180GB for Windows and some essential s/w
D: SSD: Samsung 850 Pro 1TB for all other s/w including games etc.
H: HDD: WD Velociraptor 10 000 rpm 450GB
F: HDD: WD Black Caviar 2TB
E: HDD Samsung 1TB for other things
G: HDD: Seagate 3TB for backup mainly.
