You're wrong.
Doesn't QD have a max resolution of 32768x32768? I don't have my
books in front of me.
Despite this, the problem with a new video card is the software
support. Many _PROGRAMS_ are hard coded to expect certain resolutions
(including the Finder).
I'm sure someone will post more info on this.
I'd like to see the card anyway - don't kill it because there might be
some software problems! Those kinds of problems can be fixed....
