From what I'm hearing there is a bandwidth limitation when trying to do dual DVI at 1600 on a single AGP card. This is why two PCI cards would be good.

As for using analog on a flatscreen... we are noticing blurriness along the outer edges of the screen that is not seen when using DVI. If it were simple to change the firmware on the Mac card I think we would do it, but if you have to go through trouble to get it done it is not that big a deal. We have been given the OK to get the Oxygen card so anything we try to get working now will be for the future. Thanks!
