7970 with two 6950's - config help

[erickprime]

I'm new to mining. I'm told I should be able to mine with these three cards at the same time. But CGMiner crashes pretty much instantly when trying to load (I'm guessing it's when it tries to create the bin file). I can run 3 x 6950's just fine. And I can run the 7970 all by itself just fine. I think I need to have two different bat files but I'm unsure how to do that. Any help will be appreciated. If anyone has a similar setup, can you share your script with me? I just need a base to start from. Thanks again!
