I'm in the same situation. I have an old ATI FX5150 card that AMD
stopped supporting quite awhile ago. It uses the open source radeon
driver now. I dual boot into Windows where I have the last supported
version of AMD's Catalyst software for the 5150 installed and between
the two drivers the difference is nearly  imperceptible
performance-wise.  It's largely due the fact that AMD has good support
for open source driver development providing documentation and manpower
that I stick with AMD cards.
