Got one more question if you don't mind! thinking about overclocking, so thinking about changing cpu to i5-4690k, motherboard to Gigabyte GA-Z97M-D3H, in this situation would every think stay the same as you mentioned above as far as the speed MHz, latency, and voltage, or things have to be changed, your comments please, thanks!

What do you mean? You had i5 4690 in your first post and probably now going to an unlocked multiplier on i5 4690K. The Z97 chipset wil give you access to BIOS/UEFI for unlocking your CPUs multiplier, but that's it. Everything else should be the same as for IMC (memory controller on CPU) and recommended setting from earlier for RAM.
If you read up here on Tom's you would also find out that 2133 MHz is the sweet spot for Intel's Haswell based CPU and i5 4670(k) is the same CPU as i5 4690(k) with only a better yield and therefore a higher clock rate at stock. Intel's CPU will either go for 1333 Mhz or 1600 Mhz as JEDEC standard and then you have to sett correct bandwidth and timing either as XMP profile or manually.
Here you have a table of "old" and new Haswell based i5 4690(k): http://ark.intel.com/sv/compare/80811,75048,75047,80810
You will see there are almost no difference, except for i5 4690 having support for Trusted execution technologies. Memory specification are identical as far as I can see and there you also have 1333/1600 MHz support. Going with faster memory you will need to set this yourself or use XMP profile in BIOS/UEFI.

You can still run 1600, I generallstart at 1866 or 2133 for new build, prices are comperable to 1600 and the wider bandwidth from the higher freqs improves overall performance for those that really use their rigs
I am looking at 3 cards of gskill 2133 ripjaw x, (CL9-11-9-28 1.65 Volt), ( CL9-11-10-28 1.65 Volt), and (CL9-11-11-31 1.60v~1.65 Volt), what is the different with latency numbers the ones after CL9? higher or lower voltage? which of the 3 would you recommend since I am going to be overclocking?? Thanks.

Tradesman1 :
No worries 
Sorry I keep on bugging you
, pcpartpicker.com is telling me this: (The G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-2133 Memory operating voltage of 1.65V exceeds the Intel Haswell Refresh CPU recommended maximum of 1.5V+5% (1.575V). This memory module may run at a reduced clock rate to meet the 1.5V voltage recommendation, or may require running at a voltage greater than the Intel recommended maximum). Now since I am going to be overclocking, is this going to be an issue or not?? Thanks for your help in advance, I really appreciate your time.

No it's not a problem, the CPU has a rated DRAM spec of 1600 at 1.5, I normally stick to the 1.5 at 1866 and under (with the exception of some high performance sticks (CL of 7-8), then 2133 and above 1.6-1.65 is perfectly fine. Intel even has a certification program where they accept the higher voltage DRAM

Depends on the individual CPU, i.e. most 4670K, 4690K, 4770K 4790Ks pretty much can handle 2133 with no problem, many other CPUs will need an OC to run at 2133
