Hi,

The ATI linux driver is plagued with problems. You may experience hangs
and crashes on logout and VT switches, high CPU utilization during
normal desktop usage, and in general poor performance with applications
that use opengl:

I don't know much about the intel 95x and 96x graphics devices under
xorg, all I can tell you is that it took until xorg v7.0RC (currently at
v7.2) and Mesa v6.5 (currently at v6.5.3) for the intel 855 device in my
laptop to have equivalent opengl performance under linux as when I would
boot to windows. See also http://dri.freedesktop.org/wiki/Intel .

HTH,
