This would be so much easier to call if I could find some 7850 crossfire benches but I can't find a single score. Quite frankly it bothers the heck out of me, I take some pride in my ability to search the internet. Can anyone for the life of them find me some numbers?!?!? All I could find was a mixed 7870CF 7850 bench, a 7870CF bench I could project onto the 7850 numbers, and an incredibly blurry youtube video that had 7850CF benches but no specific settings.
Yes, 7850CF cannot be expanded(2 gpu max). Yes its prolly gonna draw another 100w over the 680.
I still think a valid comparison can be made between the two setups as they both run about the same cost and use the same power connectors. So let me hear your thoughts, which would you get and why? Which wouldn't you get and why not?
