The Quadros lack the CUDA strength and cost too much. Get a GTX770; 780 or 780ti. These cards are reasonably priced and does the job
that card should work as its on the System requirements | Adobe Premiere Pro
but premiere doesn't take advantage of the advanced features in quadro's, and a similar performance quadro vs gtx may cost 5x more. so you are better off saving your money and going with a gtx. the gtx 950 would be about the same performance as that K4200, but alot cheaper. a gtx 970 about 2x more powerful, but still half the price.
