hi there! newbie arrived ;) thanks for the helpful discussion...

I am about to buy an X5690 or W3690 – just one question left:
Can I mix RAM sizes?? E.g. changing my actual constellation of 4x4GB/1066 to 2x16GB/1333 + 2x4GB/1333...

I guess it's not possible to use 2x16/1333 + 2x4/1066... or would they just be "clocked down" to 1066MHz then?

Yes, you can, as long as the RAM can fit the cMP, the only hard limit is that you cannot mix RDIMM with UDIMM.
