2 grfx cards & 3 monitors

[nichos]

This card SLI EVGA GeForce 9800 GTX runs two 19" flat monitors.

Can I add an SLI 6600GT MSI to run a third similar monitor, and will the desktop & FSX spread over the three monitors?

No those old cards must be the same GPU.
Are you saying you have x2 9800 installed in sli already?
