RAM advice - help!

[respawn]

All I have left is to buy the RAM, this is what I bought in the last week ready to build:

Seagate 1TB drive
Liteon DVD burner
Corsair 400R case
GPU - MSI GTX 660
power supply - 750w modular
mother board GA-Z77-DS3H
Samsung 840 Series 2.5 inch 120GB SSD
Intel Core i7-3770 Ivy Bridge 3.4GHz
Microsoft Windows 7 Professional SP1 64-bit - OEM

I am having some issues/confusion on the best choice of RAM.

For instance, I am trying to decide on which of these:

http://www.newegg.com/Product/Product.aspx?Item=N82E16820233366
Thinking of getting 4 sticks of these for 32GB. They will be on shellshocker in 2 hours.
I am just assuming $50 each for $200 total. The specs being:
DDR3 1600 (PC3 12800)
Timing 10-10-10-27
Cas Latency 10
Voltage 1.5V

But is that too slow? For about $30 more ($230 for 2 order) of
http://www.newegg.com/Product/Product.aspx?Item=N82E16820148657
I can get these specs:
DDR3 1600 (PC3 12800)
Timing 8-8-8-24
Cas Latency 8
Voltage 1.35V

To me, it seems to be a lot more speed, no? And it isnt even on sale...

Any words of wisdom?

You posted this on the memory forum and I posted a reply. Forum rule is no cross posting.

I posted in here first then figured I would get a better response in RAM forums. I tried to delete but dont see an option to do so (only edit). Why can't we delete our own posts? If a mod would like to delete this thread, please do so...

Get for $230

You're not going to see a difference between CAS 10 and CAS 8 unless you run SuperPi for fun. Get whichever costs less when you make the order.
