  1. I think #1 is better.

    a) CAS latency of 7
    b) same bandwidth of 1600 as #2
    c) lower operating voltage @ 1.5v (cooler)
  2. Best answer
    +2 For the PI Series RAM.

    Tighter timings, lower voltage and $10 cheaper.
    Speeds over 1600Mhz are only useful if you go past 200Mhz FSB when overclocking.
    If you do decide to do that, you can easily overclock the PI series by dropping it to CL8.
