Whats the cheapest, can be used, equipment setup for 4 monitors on PCI-express motherboard? Currently I use Matrox 450 agp 32 mb and Matrox 450 pci 32 mb. This setup is super cheap and works great. I am looking to mimick that onto the pci-express platform. I have a quad matrox PCI m200 i belieive but for some reasons it refuses to work properly. I am thinking some kind of Nvida pci-e dual monitor plus nvidia pci dual monitor card? Thank you for any help.
