Hi, I'll be getting a Mac Pro 2010 with a single 5770 and while I'm still shifting around ideas about what I want to do for a GPU upgrade, I'm curious if CrossFire or CrossFireX (are they the same thing?) would work officially in a 2010 Mac Pro without any potential for their to be damage done to the Mac Pro in any way. If so, can it be done without the CrossFire bridge like the newer cards - without any damage in anyway to the Mac Pro? This is, of course, with in Windows. I've Googled around and found a few threads, but nothing really definitive, some saying it works, but only with much older CCC drivers, others saying it doesn't work. Anyone have any definitive answer on this, and if it would cause damage to the Mac Pro in ANY way? Thanks!
