It is nice that you can swap the triple head functionality to dual head.
The newest version can output 75Hz in 3072x768 mode.

mac news sites that compared raw graphics performance saw no advantage to the 4500 over x1900. i have not tested them.
there is a big difference between the 7300 and the x1900- the x1900 is much better. ( i just upgraded a theatre show from a 7300 to an x1900 - with a vast improvement )

just because it says the newest triple head will do 75hz at 3072x768- does not mean it will work. you will have to test it for yourself.
and i would not ever recommend that anyone does this on pre-intel machines - they are just not powerful enough.

there is also the vqs-01 which i have been told has been used successfully on shows in london

this has 4 outputs.
