can i use two different cards without two moniters and without having to move my moniter cable around
Unlike the losers that posted before me, i will give you a solid answer.
Situation A) Two video cards, each in a separate computer, one monitor.
Yes you can do this. Simply purchase one of two things.
1) a monitor with selectable inputs (input 1 is generally HD15 cable type, and input 2 is BNC connector style). Connect the two cables to the monitors and away you go.
2) purchase a switch box that can switch between two or more inputs (including mouse and keyboard) and control it with the one monitor and one set of HID's.
Situation B) Two video cards, one computer, one monitor.
Again you can use the single monitor with multiple input scenerio (i believe many panasonic monitors have multiple inputs).
Again you could also purchase a switch box which switches vga channels.
The problem with Situation B is that with two video cards in the one computer, you get the multi monitor effect. One large desktop spanning two displays. I guess that could be handy if you wanted to "hide" what you are working on with one channel, and then swap between them, similar to a virtual desktop under X Windows.
This would be difficult to maintain.
Read up on how multimonitor works with cards designed for it, like the Matrox G200MMS and G400(Max). Also the NVidia GeForce2 MX, and the newly announced ATi RADEON VE.
I hope this response could be of more use.
