Hi all: I am about to sink the bucks into a 30" display, and have realized that I also need a new graphics card in order to be able to use it. (my g5 from 10/03 has a Radeon 9600 Pro with 64MB of VRAM currently). It seems there are several options but I'm a little lost at the difference between them: Any reccomendations on what card to get? The 9600 Pro with 256? Someone else recommended the ATI X800, which is a lot more expensive, but is it worth the price because it makes a difference? And most of the Apple literature seems to mention the NVIDIA GeForce 4500 card or NVIDIA GeForce 6600 card...? (I do video graphics work, so if the difference is worth it, I might as well just deal with it and pay it...) any thoughts out there? thanks!
