hi everyone, im a newb here and to macs in general.
on to my question...
why does it state that the 30" cinema display requires the nvidia cards? from what ive been reading i cant find anything that explains WHY.

also, do the ati's support dual dvi inputs?

lastly, if any of you do have the nvidia cards installed on your pm g5, could you please post photos? or if you run a 30" display, could you post pictures of the input connection, please?

thanks all

The 6800 is the only Mac card that has dual "channel" DVI (not as in 2 ports, which it does have as well, but dual DVI signal through 1 port). The 30" has so many pixels to fill, a normal single DVI port cannot handle it.

Driving Force
The 30-inch Cinema HD Display is so big, it requires the next level of graphics technology. The NVIDIA GeForce 6800 Ultra DDL graphics card delivers, with the most advanced graphics engine available for Mac. This card includes dual link DVI connectors to deliver up to 2560 by 1600 resolution over each port. Even better, with two connectors, or Dual Dual Link (DDL), you can drive two 30-inch displays, for the ultimate creative canvas. This $599 card will be available as a built to order option and as a standalone kit in August 2004.

As of right now, no, not officially. At a conference in October ATI was powering a 30" and an old ADC 23" of a X800 card. So, my best guess is that ATI will announce a X800 for mac at MWSF, so if you are planning on getting the 30" and not want the Nvidia card, wait untill MWSF before you commit.

the wording got me :(
i read it over and over and it still didnt sound the way you made it sound.

i dont really have a preference either way. my pc's run ati's b/c im a huge gamer and they've never let me down yet.

i got the dual 2.5 b/c im trying to break out of the 9-5 mold and get into something more entertaining. primarily, motorcycle videos and digital imaging

thanks again

And, if they follow the course set in previous years, they show it in October, announce it at MWSF then give out no further word on the matter until May or so when they cancel it and say instead they're coming out with the X850 due in August.

Well, they announced the Radeon 9800 Mac Special Edition 256mb card there last year, and it came out reasonably after that, I think maybe a month, or two at the latest, I don't remember.
