I've seen this, but it seems to be making a point regarding OpenCL, not OpenGL - now I'm a bit of a noob when it comes to this stuff, but as far as I'm aware, these are two different things.
The reason that I ask, is because when I build my Hackintosh, primarily it will be for video editing/motion graphics etc. and I really want to go for power. One of the plugins that I really want to use within After Effects relies on OpenGL for it's functionality - (Element 3D by VideoCopilot) - and If I was spending all of that money for such a big build, I wouldn't want to get a really really good hackintosh that doesn't do one of the major things I need it to do.
If you see what I mean?
