I just stumbled on something new: apparently NVIDEA is releasing now specialized drivers to improve stability and performance of creative applications, such as video rendering, foto editing etc.., a bit an equivalent like NVIDEA is doing for a long time for games, the so called "game ready drivers". I have not tried them out yet, I do not see Vegas and Davinci mentioned, but others like adobe products, blender, cinema4d are.
