So I searched around and couldn't find anything specific so here is my question. I currently have a G5 with a 23" and a 9600 pro, I am very happy with it. However, I am looking to upgrade my graphics card sometime soon. One of the factors I want to consider is what would be needed to run dual 23"'s--while I may not be able to afford it right now, I would someday like to have that set up. So what should I be looking into for something like this? I would like to be able to run games like Doom3 and at the same time also have OS X's GUI run smooth even if it's on dual 23" displays. Your insight is appreciated!
