 From my long past with opengl I only know there's always issues,  
regardless which brand you choose. Main disadvantage of ATIs is that  
several of their cards/drivers dropped proper (fast) frontbuffer  
drawing. That's a feature being dropped in the Blender UI anyway, and  
it has issues for more graphics cards too.

Apart from the frontbuffer issue, ATIs perform nice. BTW; ATIs in macs  
perform excellent on frontbuffer drawing, so it's really a driver  

In the Blender code we now have 2 hacks to bypass nvidia issues we  
discovered. At this moment there's a disturbing amount of reports on  
latest nvidia drivers crashing Blender...

Conclusion; it doesn't really matter, for as long our devs have same  
type of cards, so things get patched. :)
I *really* still would like someone collecting a "actively supported  
HW" list.
