Ordering new upgrade build in an hour. Gigabyte vs ASUS + RAM

[wbcman]

Hi all,
For the last days I've decided to make a new i5 2500k build, and I have two final builds to choose between.

I do live in Norway, so choices between shops are very few. But basically the following two are the choices I have:

*LINK*
2500k
ASUS P8Z68-V PRO/GEN3
Kingston DDR3 HyperX 1600MHz 8GB, Kit w/2X HyperX 4GB DDR3, CL9-9-9-27 (1.65v) (This thing has XMS AFAIK)

OR

2500k
Gigabyte GA-Z68XP-UD3P
Corsair Vengeance DDR3 1600MHz 8GB CL9 Kit w/2x 4GB XMS3 modules, CL9-9-9-24, 1.5V, Vengeance Heatspreader, 240 (Can be replaced)

I can only choose one of those two setups, since the first one is an already set up build which includes everything, and the other one is the best i can for the price range I am in.
In addition to those I am getting an 850w PSU and Silverstone Raven RV02B-W v1.7 both on sale. I know the 850w is overkill but its 50% off anyway.

TL;DR
Is it worth getting the ASUS P8Z68-V PRO with the Kingston 1.65v ram insted of Gigabyte GA-Z68XP-UD3P with the Corsair Vengance 1.5v?
The price difference is minimal (About 15 GBP).

I appreciate quick response, since I have to place the order before midnight to get the sale. (10:26 PM atm)

Thanks in advance.

Giving the the first build a shot, and hoping the 1.65v ram won't damage the the mobo.
