So what justifies the enormous price difference? The majority of the costs result from customer support and driver development. No OpenGL workstation user is allowed to be left alone with his problems, where it's the complete opposite for the gamer. Additionally, it takes a long time before OpenGL drivers can be certified as "stable", so the manufacturers pass these increased costs on to the customer. Why does no-one complain? That's easy: workstations for engineers and designers make a considerable contribution to creating value in the production process. Procurement costs are of little importance, since the workstations are a business expense, and mostly pay for themselves within a short time.
