To explain low latency first, in a brief and simple way, every chip you buy comes with what is called a clock rate, or how fast the chip will perform operations in your computer. Low latency means that the chip will actually run faster than this clock rate without having to overclock it because of the ultra high frequency the chips run on. So your computer runs faster. The question is, how much faster and does it make a noticeable enough difference in performance to justify the cost?
Without getting super technical here, when tests were conducted on various high end systems, which is where you need your highest performance boost, the improvements with low latency RAM chips came out to a meager 1% improvement in speed over regular RAM chips for the cheapest of the low latency chips and only a 3% improvement in speed over regular RAM chips for the most expensive. These tests were conducted on numerous high end systems with similar results for all.
