Do i need SLI to run two video cards with dual display?

I am looking to buy another graphics card, with a PCI interface. I already have an NVidia graphics card in my single AGPx8 slot.



Do i need to have SLI in order to run both of these graphics cards and use dual display?



If so, is there any other way i can run two displays?|||Check your Nvidia card for Multi Display Support

If it says that or Dual RAMDACS then it can support 2 monitors by itself
