Right now I have a single Sapphire HD6950(2GB)(Model: 100312FLEX) and I wanted to get another one to run crossfire. The problem is, on newegg the model is out of stock and the other similar model is deactivated...I know you can run crossfire with different models, but what should I look out for to make sure they're running efficiently?
Should I just make sure the clock speeds are the same or what?
