Hi, I'm a developer, so I can only tell you what is "THEORETICALLY" possible in my opinion. ;-) I've been experimenting with using OpenGL to accellerate HDV Playback, and using the ATI Hardware in my Laptop with the fglrx driver I did have some problems getting the last bit of performance out of it, either the fglrx driver is buggy, or my Hardware has to little Video-Ram, or both. ;-) Other than that, as far as I know, cinelerra only utilizes OpenGL for Playback, but not for Rendering, so investing in GL Hardware will not shorten your render times. And before going for a "Workstation" Product, I'd rather give a "Consumer" Version a Try, they are not to shabby either, and much cheaper. Other than that, I have no Idea about how different cards compare from a performance point of view. Be aware though that you will mostly use the "Fragment Shaders" of the GL card for Video, and not much of the other features. Benchmarks would be nice though.
