6870+6850 crossfired

post #1 of 4
Thread Starter 
Im looking to buy a second card and crossfire them, and newegg has a gigabyte 6870 for 219 right now. I currently have a 6850 in my rig. Would I see more of a gain in performance If I ran a 6870 as my main GPU crossfired with a 6850, verses just 2 6850s. Help would be much appreciated, I cant seem to fine much info on this googling.

You'll get the same performance as 2x 6850.
CF downscales to the performance level of the slowest card.

Even the amount of shaders the card uses?

As seen in this asymmetric crossfire review, 5770+5750 is between 2 5750s and 2 5770s in performance. So I'd imagine a 6870 paired with a 6850 would yield better results than two 6850s.
