I currently crossfire two 7770s, http://www.newegg.ca/Product/Product...82E16814127687
Brother just got a new card and is willing to give me his old 7850 http://www.newegg.ca/Product/Product...82E16814121623. I know for sure its better then one 7770 but is it better then two?
I just don't know if crossfire just doubles the amount of specs of a card or only takes certain parts, iv never really fully understood cross firing.. it just kind of happened when I got an extra 7770 for free.
