The issue was about 6 or 7 years ago, and being burned at the time meant losing some hard to earn cash. The issue was enough to cause BSODs and lock-ups with the program.
Today they seemed to have fixed the issue so I went back to ATI, but I'm no longer in that side of the business anymore either, so it doesn't matter.

Actually John I had OpenGL problems with my ATI 5870 just a few months ago with one of the Catalyst driver revisions. As I said before OpenGL support in AMD/ATI's drivers has been hit or miss like a lot of other things with AMD lately.
We won't even get into the transparency texture shimmer problem that plagues ATI and games that use older game engines.
