Hi, Im thinking of installing a second video card in my powermac g4. I currently have the gigabit ethernet model with ati rage 128 pro. Could I just use any PCI or PCI express card with VGA? Does it matter if its windows or mac? Which cards would be mac compatible? I just want to use baisc dual monitors, so its cheaper to buy a PCI card than the ADC adapter. Also, I plan to upgrade to a dual core powermac g4 in the near future, so will the card still be compatible? Can you please offer your advice about which PCI or PCI express VGA card will work well with powermacs. Thanks.
