CAS Latency 9 vs 10

[Hexley]

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

and

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.

Not super sure the diff here but I just bought some 10s so hopefull there is not that big of a diff.

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.
