I read somewhere that you can crossfire similar cards (such as a 7850 and a 7870) i want to know if that is true, and if it is what cards can I crossfire with a 7990?

a c 165 U Graphics card

You can Xfire with an HD7950 or HD7970 or HD7990. Although it will not be worth it.

Since the 7990 has two 7970's on the same board, it is already in crossfire. After 2 GPUs, there are diminishing returns. 2nd not worth it.
