Variations command in PS CS5?

Question

I'm coming from PS CS3, and do not see a Variations command in the Image>Adjustments menu in CS5. I have found a reference to it on this Product support page: <http://help.adobe.com/en_US/photoshop/cs/using/WSfd1234e1c4b69f30ea53e41001031ab64-7646a.h tml>, but that command is not available in the menu on my machine. Thanks for any help!

What do we sacrifice if we choose to run in 32-bit mode? I assume there's some advantage to running in 64-bit mode, such as being able to use more RAM (great for me, with my 16GB RAM on a Snow Leopard Mac Pro).
I'm annoyed by the need to switch between 32/64 bit modes, but grateful it's a possibility. My problem with it is that I'll forget I made the switch, and, days later, waste time looking for a feature that's not available in that mode.
From a user's point of view, Adobe's workaround is good to have, but isn't ideal, because:
user has to remember to switch modes
user doesn't know what's "missing" in one mode or the other
I think it would help me better if Photoshop:
warned me that I had just started in 32-bit mode, ideally in a way that doesn't stop Photoshop from operating normally (i.e., don't pop up a dialog box that must be clicked. I wouldn't want automated processes to stop just because of that warning). A pop-up that doesn't block or halt normal use would probably be good
showed the grayed-out items that would be available in the other mode. Ideally, there'd be a little note icon next to the grayed-out Variations. Clicking it would bring up a note telling me that I can switch modes to use this (and how to do it).
That would be awesome.
Still, I'm glad I found this thread, and glad I could use Variations today -- it was a real time saver.
