I understand that for crossfire to work, you have to be using two or more of the same model video cards (aka two 6850 or two 5970).
But I was wondering if there was a big difference in using two of the same models, but different manufactures. Or, if there were differences between using a mix of modified cards.
Example: I am looking to buy a Sapphire HD 6850 Toxic which has a higher core clock, effective memory clock, and other minor adjustments to the card. I am then looking to crossfire later down the road.
Is there a problem running a crossfire with a Sapphire HD 6850 Toxic (with adjustments) and with a XFX HD6850 Black Edition (different adjustments) or a Gigabyte HD6850 (with no adjustments). Or do you get the best results using crossfire with identical cards from the same manufacture?
I hope I didn't confuse too many people with this question. But thanks for any help.
