Do I need identical brands for cf to work?

[tawilson]

i have a sapphire x1900xtx and was hoping to get a cf edition card soon, but newegg doesnt have any more cf edition sapphire cards. will another brand work or do i need the same?

Different brands are fine.

What mother board are you runing?


PS. just to be on the safe side make sure that the second card also has crossfire.
