Perhaps, but *every* time I have to deal with ATI cards, it's a royal
pain. Esp. since the Catalyst drives is now "replaced" (except it wasn't
available for Linux, when I was trying to use it in the late fall. I had
to replace a couple of users' video cards with *old* NVidia ones, after I
rebuilt them as CentOS 7, because I *could* *not* get them to respond
properly to their visualization software, nor to one's 27"? 29" diagonal
monitor; it wouldn't support the video mode.

At least I *can* rebuild it, NVidia does support it that way, and the
rebuild always works.
