Question 690388, "http://superuser.com/questions/690388/why-do-workstation-graphics-cards-cost-far-more-than-equivalent-consumer-graphic", was closed by a moderator as too broad.

I can't quite see how the scope of this question is too large. It asks a well-defined question, has received several upvotes (including one after it was closed), and is not a shopping recommendation question. Assuming that this question genuinely is too broad, why is it so and what should I do to narrow its scope?
