Hey,
Nvidia Quadro, and AMD FirePro cards have been designed with workstations in mind, so yes they are made for CAD. I don't do too much CAD (I mainly use Sketchup with Maxwell plugin for rendering) but I had a Quadro 600 and it met all my needs at the time (although its an entry level workstation card). I don't know what you mean by "bring the data into a regular computer with a good gpu", as the Quadro GPU's were designed with CAD in mind (so they are "good" for it) and should handle it without requiring another another pc with a different GPU.
Hope this clarifies things!
