I getting a new gaming PC and have the build pretty covered apart from the RAM.
I will be using it for gaming at most and I don't plan on doing video editing or streaming.

Currently the build is planned with G.Skill Aegis 2X8GB DDR3 1600MHz CL11

However, the CL11 makes me feel uneasy, so I thought about paying extra to get an equivalent CL9 version. I've seen the benchmarks, and that the improvement is only minor, but I'm getting a new machine once every 5 years so I'd like to get the most out of it.

Alternatively, 16GB is a bit of an overkill for the near future, so I could possibly go with a higher quality 2X4GB (I assume 2X4 is better than 1X8), for the same price or even cheaper.
My preference for 16GB comes from thinking about the future, not a current need.

The CPU and motherboard I plan to get are Intel Haswell core i5 4670K and Gigabyte GA-Z87X-UD3G Socket 1150 Z87 Chipset.

I don't mind paying more for better, but I don't like spending extra money blindly - so your input will be appreciated.

Thanks.

 
You won't notice the difference in performance between CL11 and CL9 memory. Very rarely is the CPU memory locked.
You are right also that having 2 dimms is important. Installing only one effectively halves the memory bandwidth of the CPU because it has two memory channels and one will be disabled with only one dimm.
8GB of memory however could be a limitation at some point. New games are already coming out with 6GB minimum requirements.
I would definitely choose the G.Skill Aegis 2X8GB DDR3 1600MHz CL11.

Well, not sure that it's available where I live (haven't found it on the catalog), but something equivalent to that costs almost twice as much as the 1600 CL11 version.
This brings me back to the original question (which it seems Vince had answered) - does it matter for a gaming-only PC?

Thanks, I'm from Israel.
Hardware prices here are a bit... off, but that's a different discussion.

If it makes no difference for gaming, I may as well stick with the original choice as Vincent suggested.
But if you have a better idea I'll be happy to know.

just select ram from a reputable manufacturer kingston/gskill/corsair/crucial/mushkin all have a lifetime warranty and are good brands
a lower cas latency will mean faster communication between your ram and cpu , i suggest a latency no higher than cas9 for 1600mz
you have many alternatives

Thanks, I ended up choosing the Aegis 1600MHz CL11.
Getting the Ripjaws-X 1600MHz CL10 meant spending an extra 85$, and I was already spending more then I planned.
Also, when I showed interest in getting lower-latency RAM the guy who owns the store told me that he would gladly take my money, but I would never see the difference.

The computer will be built today/tomorrow, so if anyone thinks I'm making a big mistake - you can still warn me :)
 
you are not making a big mistake , i would not have bought the ram from a local store an extra $85 is ridiculous , however you will be fine as long as the guy assembling your pc knows what he is doing and does not overcharge you , hope it all goes well for you , all the best

Legenda in Aeternum
If seriously thinking 1600/11 (1600/9 is the normal entry level) might be able to save some money and get better performance by going to 1333/9 which will provide better overall performance than 1600/11...or as an alternativve migth check 1866 sticks, they are often the smae price point as 1600 sticks
