Of course this card is overkill for most trading, but if you use your computer for other functions this could be a fit. Nvidia Quadro FX3800.. if you don't already know this card, please look up the specs. Card is used, but certified by Dell. There is a Dell warranty until January 13, 2013... though I don't know how I'd help you honor it unless you were local... probably won't need the warranty, though... Quadro cards are VERY reliable and long lived. Card has 2, Display Ports, 1, DVI port. You can run 2 monitors using any combination of the 3 ports. It's quiet and the display is excellent. $225.00, and you pay actual shipping. PM if interested.
