Duff-Man says...when I had my Dual 800 Quicksilver I ran 3 monitors for a couple days just to try it out. I had gotten a pci radeon card to replace the rage128 one and as I also happened to have someone's monitor here at the time I just couldn't resist trying it out with all three running. Yes, it works just fine, all plug and play, you should have absolutely no problem with it......oh yeah!
