In Vegas? I doubt anyone has used the Quadro in benchmarks- I haven't seen any.
There are reports of issues with previous generation Quadros in Vegas and disappointing performance. I don't think there is any upside in using a workstation-oriented card in Vegas for video editing so unless it's cheaper would skip it.
At this website you can compare video cards and their GPUs. Keep in mind that there are both desktop versions and laptop versions which will usually say mobile. The two versions do not have interchangeable benchmarks.
