I downloaded it just last night and much to my disappointment there's an Opencl issue that precludes me from using it. It's insane how many nasty issues I now read about in their forum. You shouldn't get caught up in massive computer drivers issues just for free software, no matter how good it may be. DaVinci is very hit and miss as to whether it'll work for you or not. Be advised. I use magix (now a Sony product) movie edit pro. Inexpensive and very good, but it lacks what makes DaVinci so awesome, which is the deep and powerful coloring tools.
