I am running a 19" lcd monitor using a ATI 7500 card in the AGP bus. It is digital and the picture is crystal clear. I have another new computer whereby the existing graphics card is built into the board. I am using a Mitsubishi 15" lcd monitor in analog mode, however it can also go digital. This computer only has an open PCI slot. I can get the ATI 7500 card in PCI bus format. Question. Will the picture be as clear using a PCI bus, vs the AGP bus? By using the outdated PCI bus will it dilute picture quality? There is no open AGP slot available. I would like to take advantage of the digital mode of the Mitsubishi monitor.
