Crossfire Question

post #1 of 4
Thread Starter 
I'm really wanting to get another 6850 and go crossfire, but I've never done it before and a little confused as to whether or not the card has to be EXACTLY the same. The 6850 I already have I bought last November and Sapphire has updated the pcb to a new rev. I don't have $160 to just throw away and hope it works, i would like some solid confirmation. Thanks in advance.

Any 6850 will do, reference model or non-referance models.. I believe you can even crossfire with a 6870, but it'll downclock to 6850 clocks therefore not worth it.
