Quadro is often considered ideal for CAD, even though Quadro cards are typically less powerful and much more expensive than GeForce cards. Depending on the application(s) you intend on using, arguments for both can be made - but if you're going to be doing some gaming, you might be able to get away with a 1060 for gaming and design work. Just know that some applications - such as Revit - don't officially support GeForce cards/chips.
