Mark:
You'll note that the 9800GT is listed there, too. nevertheless it isn't
supported. I was told that current GPU software required a Nividia
Fermi or later GPU, which leaves out the entire 9xxx series. See
http://nouveau.freedesktop.org/wiki/CodeNames/
Re upgrading to C7, I can see how you may be nervous about that, given
the number of things changed. I just upgraded my personal desktop during
Christmas week, seeing as how I never rush into upgrading to a new version
until it has had time to "settle". There are a lot of differences, but
i'm learning to deal with them. When my old system gets old enough that
a lot of newer stuff will no longer build, then it's time for me to do
the deed. then all I have to do is steel myself up for a week of putting
it all back together. :)
good luck, Mark!
Fred
