It's because those applications are supported by the Graphics Card manufacturer on those cards and they will fix issues with those drivers if there is a problem with any of the supported applications. If ATI is called with a problem that is experienced in SolidWorks because of the drivers on their Radeon card, they will not fix the issue because ATI does not support that application on the Radeon. That is the big advantage to using a workstation class product, and that is why people recommend the more expensive, but historically more reliable, workstation class products for workstation class app use. This is also why these cards will stay on the application vendors certification lists longer.
Good advice which brought me to the solution. Although the Radeon does
