Running AGP and PCI Dual heads together

[Jules]

I have Matrox G400 AGP 16 mb dual head for twin screens and want to expand to 4 screens. I believe I can put in the G 450 pci 16 mb dual head to achieve this aim. I need to have windows desktop extend over all 4 screens - does anyone have experience with this setup?? or any other alternatives?? Running win 98 SE O/S

I've run virtually the same setup but on Windows 2000, no problems at all. Never tried it on 98 though.
