I have a 3rd gen iMac, 24" that I use to edit on, I like it, could use some expansion, but external drive work fine.

Problem is, we all know Color just plain sucks with these Nviddia cards, my copy of color is almost useless, slow renders, slow response, what do you expect, it does not really support nviddia.

So with these new ATI cards, is this something worth getting? Will a 256mb ATI card iin an iMac do better than a 3rd gen 24" with 3GB memory?

4Gb mem sounds great, glossy screen sounds good, until you put it next to your matte LCD, but what about this card and Color/Motion?.

I didn't specifically see the new IMac's card listed but the apple website said...

* The standard graphics card in any Mac Pro, 17-inch MacBook Pro, 24-inch iMac with Intel Core Duo, or 2.5GHz or faster Power Mac G5 Quad:
o ATI Mobility Radeon X1600
o ATI Radeon X1600
o NVIDIA GeForce 7800 GT, 7600 GT, 7300 GT, 6600, or Quadro FX 4500
* A display with 1680-by-1050 resolution or higher
* A three-button mouse for full functionality

The following are recommended for all applications:

* 2GB of RAM when working with compressed HD and uncompressed SD sources
* 4GB of RAM when working with uncompressed HD sources

I called Apple Support, they did not know. I am assuming that it will take a little time for them to update the requirements page, I was wondering if there was any real world experience form someone on the board.
