Finally, my Dad's upgrading his mac. We know it's going to be a G5 (probably the dual 1.8Gig) and amazingly he's discovered that he needs more desktopspace. Is it (still?) possible to add a PCI graphics card to the AGP for another monitor? Is there a realistic limit to this considering he's only using protools and not being particularly graphics intensive?

So far I'm considering the radeon 9600 and 7000 cards. They'll also need to be OSX 10.3 capable.
