I currently own a 6870 and was considering upgrading.

My initial thought was to get another 6870, but then wondered if I might get similar performance from a 6850 for a bit cheaper.

I tried finding data on the subject but nothing in the way of reliable data or benchmarks could be found. I was hoping that some experienced members of the TH community could help out. :D

while you can crossfire the two different cards, it is always best to get two cards that are the same model and clocked at the same speed.

it will work and amd supports asymmetrical crossfire but if the game doesnt support it you could wind up with 6850cf performance and even if the game does support it you are more likely to experience microstutter that with a symmetrical cf setup. to me it doesnt seem like its worth saving the few bucks by going with the 6850
