I need some hardware advice. Trying to get a HP 8000 Elite to run 3 monitors. I currently have 2 Nvidia 8400 GS PCI-e cards. Each card has 3 ports (VGA, DVI and HDMI) but only will run 2 ports at a time. When I install both of these cards into the PCI-e slots, only 1 will work.
What card or cards will work in combo on this desktop so I can run 3 monitors
