Had 3 monitors running just fine in windows xp pro. Went to 64 bit with my new computer. Before I had a 6600GT and radeon 7000 driving the monitors. My new dell came with a radeon x1300. Im trying to use the pci 7000 but cant get it to install. Is the fact that I need older software to drive it a problem? I'm trying to avoid having to buy another video card.
