So what!? It has been proven time and again that there are very minimal gains in performance above 1866Mhz. Who really wants to pay double or triple the amount of money on extremely fast memory that doesn't improve the gaming experience?
Computer technology advances faster than anything you know. Games can take years to produce, so you will never find a game that can fully take advantage of the latest hardware. The timeline is much different. RAM has a greater purpose, and once the bandwidth can be applied in more ways, you will know why it is necessary. If DDR3-1866 is the fastest we will ever need, a lot of time and research has been wasted of DDR4. But there is a reason the limits of DRAM frequency will continue to be pushed and you will continue to read more about improvements; though that reason may be ahead of its time for some. Years past many believed a Core 2 Duo with DDR2-1066 was all we needed for gaming, now people think an i5 with DDR3-1600 is all we need for gaming, notice how this changes in the next couple years..
It has always been a MHz war, it has always been about pushing limits, this is what drives technology and advancement.
