I'm buying a Gigabyte z68x-ud7-b3 motherboard, and i have been looking at getting G skill ripjaws-x 2133mhz ram, however theres 2 options available with different cas latency's. 9-11-9-28 and 11-11-11-30, the latter being $50 cheaper. Is it worth the extra $50 for the difference in cas latency? more then likely will overclock the cpu.

In truth, probably not!
The differences between the timings will be dwarfed by other system upgrades costing $50.
So perhaps save your cash and put it into a faster HDD.
