so i was thinking of using two card and get six display
can i SLI or Crossfire and get six display
Actually you can run 4 displays with that setup but not in surround or SLi. You would have to manually disable SLI and plug two monitors in each card. You wont be able to use all three outputs per card. Typically you can use both DVI or one DVI and one HDMI per card. Get two cards with DVI, HDMI, and DisplayPort and you can run 6 monitors. You cant do it in SLI mode or in Surround mode. But you can run 6 monitors in extended display mode. I've done it on a couple of workstations for local clients.
If you run SLI or CFX you use the outputs from the primary card. If you disable SLI or CFX you have multiple independent GPUs and can utilize all three outputs per card. I've been running multiple monitor systems like this for over a decade.
