You don't say if this this is for windows or linux or some other OS. While I've never set up FG with multiple monitors, I've configured 4 monitor systems on linux.
In general, you can't used more than two graphics cards with XFree86. This appears to be a hardware limitation of bus speed or interrupts, at any rate, it doesn't work. To get three monitor you will need a two GPU card and one GPU card. The BIG problem is that X doesn't support 3D exceleration, at least not if the monitors are bound together into one virtual monitor (the mode we required for 4 heads). Configuring the XF86config file is not for the faint of heart on such a system. Also, forget using an AGP card, you have to use PCI cards, as X will not work with a mixture. A "two headed" card really is a one GPU card with a split frame buffer and a 4 headed card is a 2 GPU card with 2 split frame buffers. I really feal that this is misleading to the consumer. X really only deals well with a one-to-one relationship with X server and GPU. If I were going to try multi-head I'd do this. First, forget three heads, go for two PCI cards. To do three heads you would need a Four headed card and a one headed card (See above) Start up a seperate X server on each card. This will require a seperate XF86config file for each card, and, will probably require that the second X server be run as root (because you can't specifiy the XF86config file unless you are root). Then, treat the second X server just as you would a second computer. A little Googling will give you instructions on how to set up mulitple X servers. The short answer is, you just specify a different vitural terminal and config file when starting it.
