Hi, my brother is about to order the new G5 2.5 and he wants to get the NVIDIA GeForce 6800 Ultra DDL graphics card to go with it, mostly just for bragging rights. He is also going to get the 23in display. I was wondering if the new graphis chip only works with the 30incher, or if it can work with any of the new displays. I was wondering because I know the 6800 has the dual-dual support and that if you only plug in one dvi connector it would only display the bottom half of the screen. Or if the 6800 had a detection for monitor size and in that case could you display 4 monitors? Maybe I missed it when reading, or Im jsut being stupid, but anything you know would help. Thanks.
