I was thinking about getting these:

http://www.tigerdirect.com/applications/SearchTools/ite...

Somebody said that they "have a CAS latency of 11, will perform more like 1333 MHz RAM"
I'm not really sure what that means and if it would matter too much. I will be using them for a gaming PC. Thanks!

If means they're slow and overpriced. This: http://www.tigerdirect.com/applications/SearchTools/ite...

Is probably the best balance of price and speed on TigerDirect, but know that it's still pretty overpriced, especially for being a Cas 10 stick, instead of 9.
(Basically the "1600MHz" is it's clock speed, the Cas Latency is the number of clock cycles it takes to withdraw a piece of information from it. 1600MHz, Cas 9 is fairly standard, and should only cost about $75 for a 2x4GB kit.)

RAM timings are written in the form of say 9-11-11-24. Each represents the number of cycles that the data goes through for processing in different stages.

The higher the numbers, the more the number of cycles. And the longer it takes. The first nymber is the most important. Its the CAS timing. RAM with a CAS of 11 will be slower than a CAS of 9. This slows the RAM down. As said, it would perform about as good as 1333MHz RAm with a CAS of 9.

These days, the optimum performance for a price comes at about 1866 cas 9 1.5V DDR3 RAM (DDR4 is different). This is what I would recommend you get for LGA1150 or AM3+ motherboards

What mobo and CPU is the DRAM for? 1600/9 is considered entry level on todays rigs. You can find that for mid-high $70s for a 2x4GB, but if it's a little higher end, there's good deals for higher freqs, like Tridents 2400/10 2x4GB for $79 at the Egg

It's gonna be used with probably an FX-6300 and a Gigabyte GA-970A-UD3P AMD Socket AM3+
Basically its a budget gaming comp.

Most you can go is 1866 anyway. I'd recommend 1866 cl9 1.5v 2 x 4gb. If you have a custom air cooler, get low profile ram.

I'd look at 1866/9 or 1600/9 2x4GB - prob best would be the GSkill Snipers or RipJaws X, both are very good on AMD rigs ;)
