    I've got the 4GB x 2 1067 MHz from my 2010 MBP - can I use these in the 2011 MBP? If so, would the performance gain even be noticeable going from 8GB 1067 to 8GB 1333 (i.e. if I can use the 8Gb of 1067, would it be worth the ~$100 to purchase the 1333)?

    Well, 8 GB 1333 is about $85 regular, but I got it for $55 on sale. I'm also pretty sure that the processors in the 2011 MBP won't be ok with 1067 RAM.

    I think maybe you should stick with the 1333. Although the 1067 may work. Just sell it with your current MB(P).

    Edited: According to Intel's website even the 2.2Ghz i7 quad-core will support 1066(1067) memory. See here.

    1066 will definitely work.
    And you would be lucky if you see a performance difference in benchmarks between 1333 vs 1066. Usually the difference is so small that in some benches the margin of error is higher between separate runs.

    +1, you should be fine with your old memory.

    Where'd you get it for $55?

    Hmm...according to that, 1600 Mhz would also work... ;) Curious...

    That's what I figured. Might pop them in tonight and see how I like it. If all else fails, I can try and swoop on the $65 deal I see in another thread and flip the 1067 Mhz on craigslist or something. Kinda curious about the 1600 Mhz now - maybe I'll wait till someone tries it! ;)

    1066 MHz will work. DDR3 is DDR3. And Intel is no longer interlocking memory speeds with processor speeds in the form of a front side bus. DMI solved that problem for them.
