I have a 9600 GT OC and I'm looking at upgrading to the 4850 X2, I like the price point. Now, I'm unclear about the card and crossfire. Do you run the crossfire with the other GPU on the card, or with a second card? I would rather run one kick ass card at a $300 or less point than run two cards. I lack X-fire knowledge, but I want to know more. Thanks for the help.
