an ATI 8500 or a matrox

[.VWV.]

Hi.

Owing to the need of purchasing a supported video-card before it's too late
for my 4.6.2, I would like to know if the X Window System driver can run
fine or not the ATI 8500. I have noticed the driver is not listed in the
'sysinstall' tool. If I choose 'ati' using xf86config or editing
/etc/X11/XF86Config, would the card work as well as a Matrox 550 one?

Thanks
