The Quadra 700, 800, 900, 950, etc have their video directly connected to
the CPU + RAM bus so they can do 40MB/sec while Nubus is regulated to
10MB/sec (I think 20MB/sec in the 840av). So you are not going to get a
Nubus video card that can beat built in video on the Quadras unless the
card
has some feature not present in the built in video (DSP chips, truecolor
on
large screens, video capture, anything that needs more then 2MB of RAM,
hardware zoom, etc).
The card you have is a very nice card, what is the problem with the
original
700 that made you want to get a newer video card?
