I'm building a computer for my dad and he needs support for 3 monitors and possibly more in the future. What would be the cheapest way to accomplish this? I know that the new core i5's have support for three monitors but I heard compatible motherboards are expensive. He doesn't need a lot of graphical power since this is going to be a business computer. Should I try to find a compatible motherboard, go with one graphics card with support for 3, or get 2 graphic cards each with support for 2 monitors. Price is the most important thing in this situation.
