I want to crossfire 2 7770's but 1st question do I need a card that supports crossfire? 2nd I received from a friend's old build. I don't have enough money atm to get a new video card like a 7850/7870/7950 and I would like to get more performance, I was thinking getting another 7770 but I have a HIS Card that doesn't say anything about crossfire support so I was wondering can I still crossfire? Thanks All- Pineapple
