I'm about to add a second HD3870 card to my system, but have never used CrossFire before. Is it simply a matter of inserting the second card and connecting that little bridge thingy? I know my MOBO supports Crossfire. Do I have to add a second set of ATI drivers, or do both cards play off the one ATI driver installation. I have the latest ATI drivers, and latest BIOS for my MOBO. Do I need to do anything else?
