Does a lower CAS Latency make a difference?

I'm debating between Kingston's HyperX Fury 2x8 DDR4-2133 memory and Corsair's Vengeance LPX 2x8 DDR4-2133 memory. They are equally priced where I am from and the only real difference as far as I can tell is that the Fury kit has a CAS latency of 14 and the LPX kit a CAS latency of 13. I've heard lower is better, but how significant is this?

It's not really super critical but why pay the same price for something slower? :-D

The sum is cas / MHz * 1000 = response time in nanoseconds if you wanna crunch the numbers yourself.

So basically the Kingston memory's response time is .5 nanoseconds slower :O Sounds absolutely minimal, but I agree with you ;-P

it adds up over millions of operations a second

Yeah it is i think :-D

The only really common use it makes a difference for is integrated gpus as the quicker speeds can help your fps.

Well since I have a GTX 760 installed, I don't think it'll be of much benefit... Oh well, bragging rights I guess :-D
