View Full Version : Dual Video Cards in PowerMac G4's?

Apr 9, 2006, 05:15 PM
I have a ATI Radeon 9000/64mb in the AGP slot of my PowerMac G4. What would happen if I put a ATI Radeon 9200/128mb PCI card, in one of the PCI slots? Would it use that card, and make me be able to play games much better? Or would it just allow me to plug in more moniters?

The only advantage of both cards is allowing you to run more monitors.

The Power Mac G4 does not support graphics performance scaling over PCI and AGP busses. I believe the last graphics performance scaling Mac was the Power Mac G3 and 604/603 PCI Power Macs with two 3Dfx Voodoo2 PCI cards in SLI.

Pop it in and run 2 monitors, you'll never want to go back!

I can plug in two moniters to the card I have. It has DVI/ADC.

But that will divide the ram and gpu power of the card, even when the 2nd monitor is off. If you use your mac for day to day use, it's fine, but when you are doing intensive 3d work or gaming, only with 1 monitor, and the 2nd off, you will notice a decrease in "muscle"!
