This may be a dumb question, but I have to ask. I'm looking for a brand name video card (good customer service) like ASUS that can drive a second monitor on my linux box. I've been told Nvidia has good drivers for this sort of thing, but it's hard to find brand name PCI video cards. Will a PCI Express video card fit into a PCI slot? I'm guessing no, but I have to ask to make sure.
