The maximum speed officially supported by an Intel Core i3/i5 CPU is 1333MHz, and most will know too well that that even lower priced Intel H55/P55 Motherboards can support a 200 BCLK. If you like to dabble in the dark art of overclocking there are a few good reasons to choose a 2000MHz (PC3-16000) RAM kit.
Firstly you have the options of lower voltage and tighter timings at lower speeds, and next you have the added benefit of higher memory bandwidth at the top speed. Last but not least though is the overclocking headroom, sure you could try to push your 1600MHz kit to 2000MHz but there are not too many kits that will do that, and you will certainly have to pay a premium.
