I don't know if this has been asked before but, I was wondering what the differences are between a 8800 series card and nvidia's quadro line up. At my work we use FX3450s for our CAD workstations. My question is why wouldn?t you just use say a 8800 GTX instead. It seems that in almost every category the GTX is better at just about half the price. Is there some features on the quadro cards that make them that much better for CAD and FEA?
