Couple questions about PCI video cards. 1. When it says PCI does that go in the normal white plastic PCI clips on the motherboard or is it a special PCI card that goes in the brown plastic clip? 2. If they go in the white plastic clips can you run more than one PCI video card at one time? If you can will it give you two desktops or will it give two desktops that react identical or will it give you two monitors acting as one big desktop? Here's what I want to do. I want to run 4 monitors on one computer. I would really like them to be 4 monitors as one big desktop not 4 separate desktops. And what I don't really want is 4 monitors that all do the same thing. I am cruising some of the Matrox dual and quad head video cards on ebay. I can get video cards dirt cheap, dual head one's aren't that much more expensive and quad heads are spendy. If I could run two dual head cards and have one big desktop that would suit me just fine. Any ideas?
