I am building a new system based on ASUS 1155 P8Z68-V DELUXE S/L Motherboard and Intel i7-2600K Unlocked Core i7 Quad-Core Processor (3.40GHz, 8MB Cache, Socket 1155)

I am trying to figure out which is the best Ram on a Value for my new PC. I was thinking about 4 pieces of Corsair CMX8GX3M2A1600C9 DDR3 XMS3 4GB Desktop Memory with total of 16GB.

Is 1600mhz a right speed for RAM? I have read that ASUS P8Z68 motherboards can take up to 2133mhz DDR3 RAM. Should I max it out at 2133mhz or it doesn't worth the money and hassle?

Thanks in advance.
(Full points are given because this is a very important issue for me)

Kingston, good value for money, never problems with overheating, even in extreme conditions/overclocking. Average speed.  But durability very good.

The choice between 1600mz and 2133mz is something you should decide for yourself, there is a difference in performance.
However if you do not need the absolute top performance for your motherboard, then the 1600mz grade RAM is still fast enough.

The cost of the RAM you choose will mostly depend on how many GB of memory they have per "stick".
If you only have 2 slots for RAM on your motherboard, you can get 8GB of ram (4GBx2) for around $60-$100 depending on the quality of the RAM. This is the standard price you should look for.
If you do not need 8GB or if you are using a 32Bit Operating System, I advise you go for only 4GB and try to find 1GB or 2GB sticks, or 4GB if you are planning to upgrade your PC at relatively short intervals.

Hope this helps.

If you want to populate all 4 slots, use RAM rated for the DDR3 standard 1.5v.    Many higher speed modules require higher voltages -- and that, coupled with the degraded waveform you'll get with 4 installed modules can result in unreliable memory operation.     Note that the system is likely to slow down to DDR3-1333 with more than 2 modules installed regardless of the rating of the modules.

If you want 16GB with the most reliable memory operation, use 2 8GB modules [e.g. ]

RAM speeds above 1600 are for overclockers, and the gains are not that much.  You would have to spend a lot of time tweaking to determine what is the fastest speed your RAM could safely run at.
