    Buying online is not an option. Any international incoming packages get heavily taxed upon arrival.

    So my options are locally sourced parts.

    G.SKILL 16GB (2 x 8G) F3-1600C10D-16GSQ
    Cas Latency 10


    Kingston HyperX 16GB (2 x 8G) KHX16S9P1K2/16
    Cas Latency 9

    Would the faster CAS Latency of 9 justify the price difference of $55? Will be installing this in the 2012 iMac and late 2011 MBP.

    Gramps, what the hell am I paying you for?
    CAS latency is (at its extreme basic) how quickly the computer talks to your ram. Lower is always better, but you're talking about a difference of 1 millisecond, so...

    Pick whichever makes you feel better.
