Hi gster, I've read more and am going to stick with nvidia. Say zbrush for example - the card doesn't affect performance (speed/poly count) but it does still output the image - and it causes problems in zbrush and mudbox too (from what I've read - delayed stroke updating being one example). There are alternate posters who say this doesn't happen for them, but there are more who say it does so it's the 9800gtx+ for me. cheers gubar
