Sorry, but I'd stay away from the 7000.
AFAIK, it's GPU is crippled (no TCL?) relative to the 7500, and it may
have detuned memory/memory bus compared to 7500 as well.
My experience with them has been mixed:
1. under RH 7.2 for Alpha's XFree86 4.1.0, it doesn't perform as well
as a 7500, though it is reasonably stable.
2. under XFree86 4.3.0, it again performs less well than a 7500, and
is unstable (hangs the machine) in certain 3D apps like "pipes".
The hangs appear to be caused by TCL-avoiding code, as one can
duplicate them on the 7500 by running the app with:
RADEON_TCL_FORCE_DISABLE=1
Look around for a PCI 9100, which I found seems to work reasonably
well, though only under 4.3.0...
Good luck.
