Which kit? (freq/CL)

Hi! I'm currently building a new rig, and have some questions about memory. This is only my third self-built computer so far, so I'm still a bit confused about this and that :)

My general specs will be:

Intel i5-750 2,66Ghz
Asus GTX460 1Gb DirectCU
Asus P7P55D Deluxe
Corsair TX-650W

I can't decide which one of these two G.Skill kits to buy, because I'm not sure how much the latency affects the kind of set-up I'm about to build. The CL7 is more expensive of course, but because I'm on a tight budget I would like to know if the difference in latency is only minor, or if it really gives a noticeable performance boost (in which case I will buy the CL7, whatever the cost).

4GB Dual Kit Ripjaws DDR3-1600 F3-12800CL9D-4GBRL 9-9-9-24

or

4GB Dual Kit Ripjaws DDR3-1600 FC-12800CL7D-4GBRM 7-8-7-24

I read somewhere that AMD builds are greatly affected by CL, vs. Intel builds that perform mostly on frequency. Is this correct?

Btw, I know i5-750 only supports 1333Mhz, but I'll OC both the CPU and RAM, so I hope there will be no problems there.

Thanks in advance!

The lower the latency, the better. The numbers you see listed are how many clock cycles it can do a certain command in. The faster it can execute a command, the faster it can get to another.

True. ^^

That said, you wont notice a difference outside of benchmarks. Get some DDR3 1600Mhz CL9 1.5v and call it a day. :)

OK, thanks for the suggestion, I'll go with the 9-9-9-24 :)

Heh, I just found a very cheap kit of 2x4GB Corsair Vengeance DDR3 1600MHz CL8 (8-8-8-24). Cheaper than the G.Skill CL9 even.

I'm a bit confused about the compatibility with my mobo though (Asus P7P55D Deluxe). Stupid question: Are the listed compatible memory modules on Corsair's homepage just directional i.e. tested for guaranteed compatibility, or do I really have to chose one of the kits on the list (if I would want Corsair's modules on my mobo)?

http://www2.corsair.com/configurator/product_results.aspx?id=1105952#other_modules

Vengeance memory (8GB 1600Mhz 8-8-8-24) isn't listed as being compatible with P7P55D Deluxe?

Thanks again for the help. Just want to be absolutely sure before I buy anything :)


EDIT. Never mind, found my answer and apparently latencies don't affect compatibility, so no problems there!
