Hello,
I am building a new system, but need the finishing touches. I want to purchase the memory today, but I am confused about CAS and speed. I want fast and stable memory.. I doubt I would overclock though. My system will consist of

Q: what do you think of build

Q: memory choice with a little explanation please?

P6X58D premium mobo

i7 920 processor

Gskill's eco series gives you good speed, tight timings, super low voltage, and good price all in a nice little package

Its CL7 vs the normal CL9 which makes it a bit faster, the 1.35V will give you a lot of OCing headroom if you want to experiment. The low voltage also tells you they are high quality chips because the average quality ones require atleast 1.5V to run stably.

For any ram you are considering, do your own homework.
Go to the ram vendor's web site, and access their configurator.
Corsair, Kingston, Patriot, OCZ and others have them.
Their compatibility list is more current than the motherboard vendor's QVL lists which rarely get updated.
Enter your mobo or PC, and get a list of compatible ram sticks.

Here are a few links:

Cpu performance is not very sensitive to ram speeds.
If you look at real application and game benchmarks(vs. synthetic tests),
you will see negligible difference in performance between the slowest DDR2 and the fastest DDR3 ram.
Perhaps 1-2%. Not worth it to me.
Don't pay extra for faster ram or better timings unless you are a maximum overclocker.

Thank you for the excellent comments. I ended up purchasing 1333 Kingston memory. I knew that I wasn't going to be overclocking and with a nominal difference in upgrading performance by pushiing RAM I decided I would go for stability.

I agree. I went with 1333, that the local store offers called Kingston valu RAM. I really appreciate your help.
