4870 ZDFC + 4870 ZWFC a match for crossfire?

[ranspilot]

Can I use a 4870 ZDFC a 4870 ZWFC in crossfire. Will the different models make a difference?

You should be fine; just make sure the clockspeeds are the same, and that you have a CF bridge (should have come with one of the cards), and that your mobo supports CF.
