Can I crossfire these together?

Solution
Yes, they will crossfire. But you may have problems since each card will run at difference clock rates and speeds. You'll have to play and overclock or underclock accordingly. It might work at first, but once you start taxing the cards you'll start to get glitches and artifacts. You should make sure your case has very good cooling if running crossfire, as with two cards, normally one card gets way less air then the other
