No problem :) the FX1700 handles every component of an Engine (including nuts and bolts), allowing for smooth rotation and modelling.

If  your boss doesn't do anything that complex then a lower spec Quadro would do just fine.  A gaming card would probably not be suitable for CAD work, I have tried using one before and it was not a great success.
