One thing you should know, a dual GPU's do not share their memory. If you have two 2gb cards in crossfire, they don't perform like they have 4gb because each card must load all the same things into their memory to create frames.

The 6970M crossfire will be faster most the time if not all the time: http://www.anandtech.com/show/4361/avadirects-clevo-x72...
