Crossfire 7970 GHz and a 7950?

post #1 of 3
Thread Starter 
I was always under the impression that with a crossfire setup, you need to have two of atleast the same series card (but could use different brands), however I've noticed some people on here seem to have a setup with two different cards like the two I listed in the title. What are the pros and cons to this?
