What could I use a second video card for?

[Noel 4,487]

I know there is some discussion here and there on this, however just a quick overview of what potential uses I could put my 2nd x16 slot into service with a retired 8800GT. If I had a second display, how could I allocate a certain part of the FSX world to the 2nd video care + screen? Thanks in advance,Noel

Noel,The most obvious answer is you can extend the virtual cockpit view across two monitors instead of one. All you have to do (I think?) is hook up both DVI ports on your (one) card so the card is sending two signals to the monitors. You then have to go into Windows, the Nvidia control panel and then select desktop extension? This is just a very general overview; I don't run dual monitors, but I know you can physically do it with just a few steps like I described above.You could also use the second monitor for 2D panels, e-charts (SID, STAR, approach plates) and other things you might need during the flight.The only other added benefit that does NOT apply to MSFS is...You can run CUDA and Physix with a second Nvidia card for other games that support it e.g. Crysis, Grid, Need for Speed Shift, etc. Having one card dedicated to physics calculations will allow the game to be more real, obviously, but also allow you to experience certain features you normally would not be able to do so without one.You can also run Folding@home apps with a second card, too.
