CAS latency 9 instead of 11 worth $25?

Question

I've been looking at this RAM for a while:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231476
as it is the highest frequency my motherboard supports, and lowest CAS latency of that frequency that's not ridiculously priced. But today there is a 48-hour $15 off promotion on this:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231552&Tpk=20-231-552&nm_mc=EMC-GD040312&cm_mmc=EMC-GD040312-_-index-_-Item-_-20-231-552
which is already $10 cheaper. I wasn't even planning on purchasing the RAM until I got an i5-2500k, because I probably won't even notice the difference from the 1600MHz I have now until then! I would be perfectly willing to pay $10 more for the Ripjaws X, but it being $25 cheaper makes me consider getting the Ares now. The other problem with the Ares is that they are orange... Which will clash terribly with my current blue/white/gray scheme. But obviously, it's not like I'll see it often, being inside the computer... Also, I am getting a SATA III SSD, and possibly 2 in a RAID 0, so the real bottleneck on loading things will probably be RAM, that's why it's so important to me. So basically, how MUCH of a difference do CAS latency and general timings make?

Answer 1

Ram won't be a bottleneck. The performance gain, which is pretty low, doesn't make up for the price you pay extra.



If you really want to, get the more expensive ones, but you won't ever notice a difference unless you're going to run tests with applications that require fast RAM such as unzipping and probably video rendering.

Answer 2

Cas Latency 11

Answer 3

In general, no the better timings aren't worth it...



Even going from 1600Mhz to 2133Mhz RAM is less than a 5 percent performance gain overall, you'd only see the difference running benchmark test software, not in actual games or most applications (except possibly the most demanding ones like rendering in 3D design applications like Maya, Autocad etc where stuff takes hours)
