I was curious, does the X800 XT come with an ADC to DVI converter? I was thinking of modifying my order from apple from the 6800 GT to the 9600XT and buying an X800, since right now I have to wait 3-5 weeks vs 2-4 days.

The only thing is, I need it to drive two DVI LCD's, and don't want to go out and pay more for a converter when the card is already $500.

nope.

Alright thanks. I decided I couldn't wait and changed the order anyway.

It does have dual dvi out though. All you would need is a dvi splitter cable. Basically splits out to two cables once it comes off the card. You could then run two displays form that cable. they had to do that so they could run the 30" Cinema Display.

You can't do that. There's a difference between dual DVI and dual-link DVI. The X800 has a dual-link DVI which allows for the 30" ACD compatibility. It does not allow you to connect two DVI displays to that single port.

Actually, I believe it does. You would need a cable similar to what was bundled with the Matrox Parrhelia card, to split to dual link signal to two standard DVI signals. (I do not know if Apple, or ATI supports this however)

However, I am talking about stripping the DVI signal from the ADC connector. ADC is simply a DVI signal with a USB bus and Power bus running on the same connector. I wanted to know if ATI provided a cable that would do this, but I found out they didn't, so I ordered the belkin one from the apple store.

NO YOU CAN'T split dual-link DVI to get two single DVI! As a2daj said dual-link DVI is for driving ONE monitor that has a high resolution above what single DVI can support. If you split it, you'll get half a screen on each monitor.

Correct. The splitter cable the Matrox card uses is something Matrox designed into their card for this specific purpose (driving 4 monitors from two physical ports, since there was only room for two ports on AGP/PCI backplane).

Some Sun systems we have at work do the same thing.

But you can't just use such a splitter on any (dual-link or not) DVI port and get two ports out of it. It just doesn't work that way.

The ATI Radeon X800 has one dual-link DVI port which will support one display, currently up to the Apple 30" (the other port is a standard old ADC port). Apple's nVidia cards have two dual-link DVI ports, each of which will drive one display, up to the Apple 30".
