When Freesync Crossfire support comes out it'll probably be botched rubbish which will run like trash. Glad i'm not on the freesync bandwagon, for now. Hope AMD's driver support improves, they're digging themselves a deep hole. Only problem is that AFAIK Nvidia still has the shovel after the 970 issues, it'll be couriered overnight to you AMD.
If its like Single GPU then it will be worth the wait! This should have been sorted ages ago though..
