Can I use more than one video card on my Mac?

I want to use more than 2 monitors. I was thinking about getting an AGP video card and a PCI video card. Will this work? I have the 2.3 Dual G5. Please provide a link to back up your claims.

Thanks|||You can add as many cards as you have slots, and usually, you can support two displays per card.



If you look at the first link below, Apple's "Power Mac G5 Technology Overview, October 2005", page 19 says:



---------



Support for Multiple Displays



Every Power Mac G5 graphics card supports two displays in extended desktop and video mirroring modes. Extended desktop mode lets you distribute work across two displays, allowing more room for viewing rich content and complex applications that use floating palettes and long timelines. For example, you can view Final Cut Pro on one display while watching the video output on the other. Video mirroring mode outputs the same information on both displays, which means you can control a presentation from one display while the audience watches it on a second display or projected image.



The possibilities get even more interesting when you connect more than two displays. For maximum productivity, extend your desktop across up to eight displays.

That last line sounds pretty clear to me!



There's also a MacNN discussion at the 2nd link [2].



You should already have an AGP video card, so you'll need PCI video cards for the other slots. I'm not sure the card I linked below [3] will work for you, but if it will, it's a darn good price for an ATI Technologies RADEON 9200 128MB MacEdition PCI card.|||thanks. are there any with two DVIs not one DVI and VGA?

|||Sorry about that i miss read the question, yous asking if it's possible to have 3 or more monitors in your mac, and to my knowledge it's not possible on that motherboard. you could get a PCI card but it's not possible to run an AGP and PCI card together. and their is no PCI card on the market that is Crossfire or SLI compatible.



::Original Answer::



From what i seen the 2.3 Dual G5 has a NVIDIA GeForce 6600 with 256MB GDDR3 SDRAM on a 16 lane PCI Express card, which can handle duel monitors with out the need for a second video card.
