    I know I've been posting a lot of threads recently, but I think it's a good idea to have separate topics in different threads, because other people would have a better time finding these threads in case they need to use the thread themselves.

    I am aware that the PowerMac G4 MDD usually comes with a 64MB or 128MB graphics adapter in it.

    My question is, what is the most Video Memory the machine can handle? In case my main computer does die, which it is, I was figuring I might be able to take my main computer's graphics card and put it in my PowerMac G4. That graphics card has 1.5GB of Video Memory. It is an ATI graphics card, and I'm pretty sure the PowerMac uses ATI graphics.

    Your PowerMac has a AGP 4x slot. No AGP card has 1.5GB of video ram. G4 PowerMacs can only see 256MB of video ram. Even if the card has 512MB. This is a limitation of all G4 Macs. The fastest card would be a flashed PC card. Some of the faster ones include the ATI X800. These sell for about $100 on eBay. There are two flashed X800 cards. The FireGL3 and the standard PC one. The FireGL3 has two DVI-I ports that can be used with a VGA adapter to output VGA. The standard PC has one VGA and one DVI-I port. The DVI-I port on the standard PC one does not work. Thus, if you want a flashed ATI X800 with working DVI-I ports, get a flashed FireGL3.

    There are of course other cards, maybe some more powerful than the X800. Before going out and buying one, see what others post. Video cards are not my greatest strength.

    Cool, thanks. You didn't have to be good at video cards, I got the information I needed. Thanks!


    I will consider this next time (If I remember), thanks.

    I've got a PC FireGL X3 flashed with Radeon X800 ROM, it's an awesome card. Two displays connected with DVI at 2048x1152 resolution, butter smooth. Overclocks well.
