Maybe good for CAD work, but not for games. Period. CAD cards may use some of the same underlying hardware, such as the chips and cores, but they also contain additional ROM code which adds in additional functions and removes others. These cards also contain the primitives for quick drawing of various shapes so they don't have to fetch this information from the software. Specific calls are made, for example, for a cylinder and the hardware already has the shape in its built-in library. They also have additional pipelines and math precision which is never utilized by the gaming hardware so it's a waste. With this additional overhead, the cards are actually slower on the gaming side and better suited for CAD/CAM and model building. Thus, we have the high price for the Quadro cards.
FYI. I worked in the hardware industry for many years, and specifically, with terminals and later graphics terminals, then much later with systems and IT. I used to troubleshoot and test the graphics circuits down to the component level. Today I'm retired from the computer industry and IT and enjoy this stuff as a hobby instead.
