How do I install a two grahics cards on a 2.8 mac pro I am planning to buy two Hd Radean 3870's to crossfire and a mac pro in july. How do I do this, do the cords to crossfire come with the card, or do I have to buy them??? Are there intructions that come with the cards that would show me how. Do I have to connect the cards somehow and is there any risk of breaking my the mac pro? Im really lost sorry. Thanks for the help.
