From reading NVidia's website, learned that Quadro NVS graphics chips are designed for "professionals" and the GeForce chips are for gamers and home use (general purpose). Further found some comments like these: = = = = = A quadro card is used for graphics design and CAD processing. It isn't meant for highend gaming Quadro cards are intended for content creation, and they are tested an optimized for that type of use. GeForce cards are intended for gaming and general applications, and they're optimized for that. = = = = = So far I have only used graphics cards with the GeForce series (e.g. 5400FX, 8400GS, etc.). From what I gathered the Quadro series are more expensive (sold as new). e.g. a dual card Quadro NVS 300 is ~$180. A GeForce 8400GS dual card can be had for $60. From a trading application perspective, do you see any added advantage using the Quadro cards versus the GeForce cards? e.g. more reliable? Pictures clearer? Refresh/painting faster?
