Using two amd radeon 7000 series hd cards in my pc

[Jimbo1969]

How do I use two AMD Radeon HD cards in my PC. Is there a "jumper" cable needed between the two cards? Any advice or Help will be appreciated please.

You will need a crossfire bridge that came with your cards or should have.The cards also have to be the same type 2 7970's,2 7950's, and so on.
