Hello, I was just wondering what the difference was between 1333Mhz and 1600Mhz, because I was planning on buying more RAM for my MacBook Pro Late 2011 and wanted to know if there would be much of a difference between them.
Got a tip for us?

^^ that.
However, i just upgraded to 16GB of DDR1600, which is sold as "DDR1333 compatible" (supposedly falls back if required).
The difference in cost was about 5-10 dollars vs plain DDR1333.

Well, nowadays the price difference is so minimal that I would certainly buy The One Spec'd for your machine, unless someone is giving you some.. ** or maybe if you are thinking of Upgrading to a newer computer and want to Swap if out to that later, then going to a higher spec may be warranted if backwards compatibility is confirmed.. 
If I were to buy 2x8GB 1333Mhz Ram for the new iMac 2012. The one that cost 1799. Would it be compatible with it, because I was reading some of the older posts and it having to be compaible.
This is my experience also.
However, if it is actually sold as 1600/1333mhz compatible, then i have the right to return it if it isn't
FWIW, it is running at 1600 in my MBP, which is "officially" specced for 1333.
