Sapphire R9 280X - Dual-X or Vapor-X

I'm trying to decide between these two cards.

Any recommendations?

Dual-x is cheaper and as long it's Hynix memory in them they perform equal.
I would go for dual-x. Is it possible to return them ones checked the memory manufacture?

I would prefer Vapor-x. If you can provide colder environment, you are able to do over 770kH/s - temp below 73'C. With dual-x I've reached only 750kH/s but it does not mind temps over 75'C.
