I have a Powermac Dual G5 @2.0ghz, with 8gbs of ram, and 2 1tb drives running the latest version of 10.5. The problem I have is that I have 4 LCD monitors that I was using with my PC. I swapped that out with my mac, and while I am no novice, I didnt take into account that I cant just put any AGP and PCI video card into the system. What I need to know is if I can use two PCI video cards both with Dual Monitor outputs, and if so, which cards should I buy, and where? I found some video cards on ebay that are PCI, and it is quartz extreme compatible, but I am unable to use it with the AGP card already installed. The person selling the cards was unable to answer whether or not two of those cards could be used together. I only have about 75 per card to spend. Please help, I cant go on using this awesome machine with only one 19inch LCD. and I cant afford to buy new monitors. Thanks.
