I am helping put together a rig that will be able to be used in a coney island to output to four monitors to display the menu on. I am having trouble picking out the hardware. Such as, what type of motherboard and video cards could run four monitors. Should I use four different cards or two cards with dual output? What motherboard even has four pci-express slots? Also, I am slighty woried about the lasting power of a rig like this. So please. Any suggestions?
