Performance-wise you will likely not notice the difference between these 3. If you're not going to OC, the fastest frequency you can run is 1333 MHz. If price is no option, throw out choice #2 because #1 and #3 have lower timings.
Between these three choices #1 and #3 are spec'ed the same except that #3 requires less Voltage. Lower V could have the added advantage of producing less heat. Given they're the same price, go with #3 - get the G.SKILL ECO 1600 F3-12800CL7D-4GBECO
