Im about to do a build tomorow, it will consist of:

silverstone 500w 80+ bronze 

cougar x6r9 case 

i5 3570k 

segate baracuda 1T 

asus z77-v 

no gpu, I will be using hd 4000 igpu on the i5. 

This computer will be used for general browsing, hd movies, hd youtube, adobe afterefects / premier, auto cad work. 

My question is what ram? 

corsair vengance 1600mhz: http://www.umart.com.au/pro/products_review.phtml?id=10&bid=2&id2=153&sid=71120

or 

g-skill ares 1866mhz: http://www.umart.com.au/pro/products_listnew.phtml?id=10&id2=153&bid=2&sid=86659

theres only $6 difference the latancy is practicaly identical and considering that i will be using the igpu that will be sharing my system ram is it worth going the g-skill for the extra speed?

 

cheers in advance.

the 1866, I was looking to flaw it but all of the stats say otherwise... by all of the stats I was looking at the voltage

So basicaly then its worth the extra $6 to go the extra speed.

I know for sure that the vengance sticks are aproved for use on asus z77 motherboards, can someone just clarify that these sticks will work 100% on an asus p8z77-v.

Cheers.
