Hmmm...Now, let it be known that I do not particularly want to do what I'm going to ask about...so, here goes.

I was thinking about hooking my computer up to both of my monitors, and then it occurred to me to ponder the following:

If a person wanted to hook up more than two monitors, usually it requires an additional graphics card, as most cards I've seen only output to two monitors. So, let us say that I have four monitors. In my system, I already have one graphics card, a nice one that I use to run games and such on my current system. This graphics card I cannot replace, because it is so new and shiny. It runs two desktops, one for games, and one for standard purposes. I merely want a cheap solution capable of rendering two more desktops for the other two monitors.

Is it possible to:

1) Run both PCI-Express x16 and PCI (or PCI-Express x1) graphics cards?
2) Run both an ATI-AMD card and an nVidia card?
3) Run both Forceware and Catalyst?
4) Run both nView and Hydravision?

No, not a practical case (four monitors FTL!), but I'm curious, and it's difficult to find articles via google because of the nature of the phrase "ATI and nVidia," especially with its tendency to summon fanboy arguments.
