Hello everyone. I was thinking of upgrading my 8800gt to a newer card, and after reading the issues people are having with the GTX 400 and 500 series I decided to start looking at AMD cards. I have heard some conflicting views when it comes to Radeons and Blender compatibility though these usually have something to do with the drivers for linux and older models/drivers of the cards. Does anyone have any experience using the newer AMD cards with Blender on Windows and do they have a significant performance advantage over the GTX400 and 500 series cards? Thanks.
Yes, i’ve an ati radeon with amd (6870) and ther’s no problem at the moment 
Thanks! That’s good to know
radeon 6950 … been having no problems until recently… the 2.57 releases make my graphics driver freeze up after using blender for ~ half an hour.
trying to fix this now… doesn’t seem to be a common issue tho.
