Lower CAS w/1333, or higher CAS w/1600?

[AgentSquishy]

I'm stumped as to which one is better. This is for a gaming build with my i5 2500k.

Here are the sticks of RAM I'm thinking about purchasing but if there is one better you know of, please share.

Bang for the buck I'd get the 1600, as it can be OC'd a bit more and sets you up for the future.
However, I doubt you would tell much performance difference between any of those choices.

Sandy Bridge is best used with DDR3 1600 cas 8 or 9.
