Corsair Vengeance 16GB RAM: 1600MHz or 1866MHz

[Cpt Nooby]

Hey guys, I'm planning to build my first PC, and I just need some help deciding on which RAM I should have.

Here is my current build:
Intel Core i5 4670k Quad Core LGA 1150 3.4GHz

Cooler Master Hyper 212 EVO CPU Cooler

MSI Z87-G45 GAMING LGA 1150 Motherboard

Samsung 840 EVO Series 120GB 2.5" SATA3 Solid State Drive

Seagate 3TB Barracuda 3.5” 7200RPM SATA3 Hard Drive - ST3000DM001

Gigabyte GeForce GTX 780 3GB Overclock Video Card

Zalman Z11 Plus High Performance Gaming Mid Tower Case (7 Fans total)

Zalman 700W PSU ZM-700SV - 80 Plus Silver

Now, the main question is, which one of these two RAMs should I get.

Corsair Vengeance 16GB (2x8GB) DDR3 1866 MHZ
(I found a shop that sells this for $110, it's $213 on Amazon)
http://www.amazon.com/Corsair-Vengeance-Desktop-Memory-CMZ16GX3M2A1866C10R/dp/B007QY87MG/ref=cm_cr_pr_product_top

or

Corsair Vengeance 16GB (2x8GB) DDR3 1600 MHz ($150 on Amazon)

Please also let me know if you find any compatibility issues. Thanks.

if you are really sure about that store, and this is not fraud or something, surely get these 1866 rams. OC them and lower the latency.
