I'm looking to expand my trading computer setup from 3 monitors to 5 or 6 and am uncertain what products to use to do this. Currently I'm using a HD 5750 card to run 3 monitors and my initial thought was that I'd add another mid tier card to run 3 more. Then I saw at AMD's website that half their R7 cards and all of their R9 cards will run 6 monitors with a DP MST hub. Is this a better idea? Which card(s) in AMD's line would be adequate to handle trading data well if I did this? As for the monitors themselves the final setup will be one desktop spanning a 30" and two 21" inch screens for a total resolution of 4960x1600, and a second desktop spanning 2-3 24" screens. Thanks for ideas.
