Thanks Peter,
In the Configuration Guide September 2013, (https://www.blackmagicdesign.com/media/6677761/DaVinci_Resolve_Windows_Configuration_Guide_Sept_2013.pdf)
it only specifies as ATI cards the firepro models (W8000 and W9000), nothing else
I run Windows with an I7 2600k and i just need a decent card to play with resolve (2k footage)
