Simple enough, what do you think is the best series? Quadro, FirePro, Tesla, Radeon, or GeForce?
what is the best video card, or GPU series for Sony Vegas? (a video editor)
quadro or firepro if ya got the doll
side note though, if i had that sort of doll i wouldnt be spending it on vegas to go with those cards. more like Adobe after Affects
Both Cuda and OpenCL is supported on Sony Vegas Pro 12
For Sony Vegas, I recommend getting either a GTX 690 or 2x GTX 680s for massive amounts of CUDA. Or, if you can wait, get the Nvidia Titan for a little less than the 690, which is supposed to be faster than the 690 (source: Nvidia).
