Video cards for multiple monitors [closed]

"Since PCI-Express cards tend to come cheaper than PCI (due to sales volumes), you may want to consider getting a motherboard that can take multiple PCI-Ex cards if you do not have an existing motherboard you have to work with.

Even if you already have a motherboard, depending on what you are doing you may want to look at dual PCI-Ex as an option, since it may be a bit cheaper than PCI-Ex + PCI, and give you a newer motherboard at the same time."
