Touch screen as third monitor

My present setup is two monitors. One has the cockpit view while the other has a moving map, GPS FMC, or any other sub panel.I want to add a third mintor as a touch screen. This way I can program the FMC with my fingers or play with the Garmin GNS530 from RealityXP.Here's one candidatehttp://www.amazon.co...30029656&sr=8-1As you can see it requires a USB connection and bingo- no need to hook up to the graphics card. Here's another one-http://www.amazon.co...8/ref=pd_cp_e_0So is this possible? Currently I have one monitor connected with a VGA plug while the other is DVI.Can I have a third monitor without it being connected to the graphic card slots at the back?Eytancomputer specsIntel Core i5 2500 CPU @3,3GHZGeForce 9800GT 512MB GPUDDR3 4GBSATA 3 hd 1TBWindows 7 32 bitSamsung Synchmaster 931BF 19" monitorMAG Proview 21" monitorThrustmaster T-Flight HOTAS XVRInsight M-panel
