Will these slightly different 5770s work in crossfire?

I bought a Sapphire 5770 about a year ago, and now I'm looking to get another for crossfire. The one I bought is discontinued, but there is another one that's almost exactly the same.

Will those two play nicely together? There are also two other Sapphire models available, here and here that have PCI 2.1 instead of 2.0. Would that be a problem? And do I even need to stick to Sapphire cards at all? I've never set this up before, so I'm not exactly sure what makes a card incompatible with another. Thanks!
 
it would not be any problem, regardless of the make they will work. 2.1 2.0 makes no dif.
