Which one to buy? Please help.

Ok so i really dont know that much about RAM's and this confuses me.
Btw im 17 and english is not my motherlanguage.

So i want to buy more RAM since 4GB isn't quite enough these days.I decided to buy 12GB so i dont have to upgrade for a
long time.I started to look for a new RAM and found a pretty decent Corsair's.

Link: http://www.portio.hr/index.php?page=artikl&id=051210120
The price is 128 USD (At least in my country)

But then after searching a bit more i found this Mushkin's.

link: http://www.portio.hr/index.php?page=artikl&id=051210195
The price is 78 USD.

So after searching on the web i find out that Mushkin is a very good company.
So i dont understand why is it so cheap when it works on 2133 MHz (latency is 10) While
the Corsair one works on 1600MHz on 9 latency.
Is it because of the other timings (TRCD ,TRP ,TRAS)?
Because i dont know what do they mean.
All i know is that the higher the numbers are the slower it goes ,so i would assume
it is slower but too much.

So i was hoping that someone could explain to me why is it so cheap.
And i would also like to know which one to buy and why.

System Specs:
Motherboard: ASUS M5A78L
GFX Card: Nvidia GTX 560 Ti (im planning to get GTX 680)
Proccesor: AMD Phenom II X6 1055T
Power: MSI PRO-550 ATX
Cooler ASUS 1225S1/D1


Thanks in advance

I recommend this kit:

Your board has 4 ram slots; leaving one empty with a 3 stick 12 gb kit will put you in single channel mode; the ram will run slower. 12 gb kits are for x58 boards only. 1333 ram is a little slower than 1600, but you won't notice much difference in speed. Your board can handle 4 gb per ram slot for a total of 16 gb.

Thank you i didnt know that.
I think i will buy the 16GB one.

but i am still wondering why is the mushkin card so much cheaper then the
Corsair one.
Is it slower or what?
Can you please explain.

The mushkin has slightly higher timings but is faster 2133 versus 1600; as the speed of the ram increases, the timings move higher to accomadate the faster speed. The higher timings are actually slower. Old slow ddr2 may have 5-5-5-15 timings which are fast, even though the ram speed is only 800. If you don't understand this, I can't help you more. Google for some ram articles. Corsair can charge more for their ram; it's up to you to decide if it's worth it. I've used mushkin ram; it works ok. Once in awhile you'll get a bad ram stick. You can run memtest to see how many errors you get; I don't use it unless I get windows bluescreens with a ram address listed.
