Hello,
I am looking to upgrade my system and am trying to figure out some details on the SLI/Crossfire thing.
I have read so much and I am more confused than ever. Different answers everywhere.

I currently have three monitors set up, two 24" LCDs and a Wacom Cintiq, all set up as a huge wide desktop.
My current setup is just using a dual head agp video card for the monitors and a single head pci card for the cintiq.

I am building a new system and want (need) to keep the 3 monitor setup, but would like to get the benefit of an SLI/Crossfire setup as well for games.
Can I put two cards in SLI/Crossfire setup and run the 3 monitors most of the time, but switch to the performance of the SLI/Crossfire via software?

Even if when I switch I can only run games on one monitor with the others black, that would be fine.
I would love to be able to run at least 2 monitors when gaming (game on one - chat, ect on the other) but I can deal with just one.

Is this setup possible, and if so is it a simple thing to switch back and forth between the configs via settings in control panel or something?

I am looking at the Rampage Formula, but am not set on anything yet. I see that board is crossfire compatible, so if SLI is better for my needs, can anyone recommend a similar spec board for SLI?
Thanks.
