WTF RU HIGH, tight cas latency will overall speed up your system.

If you were to run a synthetic benchmark it would be able to tell the difference. If on the other hand you took two identical machines, with the only difference being one had memory with cas 9 and one had 11, no, you wouldn't be able to tell the difference.

There has to be a balance, but most of the time you will never notice the difference.

DDR2 has lower CAS latency than DDR3, is DDR2 faster?, nope.

With ddr3 it's a pretty good balance between speed/latency. Latency is overall more important then speed for gaming once you get to about 1333mhz or higher. I see DDR4 2400 CAS 15 RAM and cringe because I'd prefer 1333mhz CAS 9 any day

 

For a little bit more money you can have a lower than average latency, and a higher than average speed from a reputable brand

Do aesthetics matter to you? For $5-$10 more, you can get some higher speed memory with tight timings. I personally use http://www.newegg.com/Product/Product.aspx?Item=N82E16820231476(got them on sale for $55 around Xmas). My little brother uses http://www.newegg.com/Product/Product.aspx?Item=N82E16820231554 which is also nice for the price. 

 

The most aggressive 2133mhz kit i have ever seen would be http://www.newegg.com/Product/Product.aspx?Item=N82E16820231518as even its secondary timings are super tight. Either way, CL wont make a drastic difference for most people. It is just recommended to try to get a balance of high speed/tight timings out of your memory.
