5 screens setup possible?

Hello,

is it possible if i have two graphics cards in my pc - for example 2 x nvidia gtx260 with two dvi-ports. will it then be possible to add a tripplehead on port 1 and then have two seperate screens via graphics card #2?

PC-SETUP:
Gtx260 I + triplehead = 3 monitor span (3 x 24") (running scenery)
Gtx260 II = 2 seperate 19" monitors (running various 2D-panels)

Will this be possible - and do the two graphics card have to be connected somehow or should i just have a motherboard with 2 PCIe-interfaces?

From the research i've been doing, i don't see why not!
You'll just need to make sure you're PC is top spec!

I'm using two video cards to run 2 outside views and two gauge displays. Card number 1 runs the forward view via a Triplehead2go and 3 monitors, plus a single monitor for the 90 degree right view. Card number two runs the two monitors for gauges. My scenery sliders are set farely low to get decent frame rates and I have made a number of tweaks but it works well enough. Don't connect the cards in SLI (Nvidia) or Crossfire (ATI) mode as it will render the outputs on the second card useless.
