I read the whole thread and have been aware of the problem with taking screenshots but since none of you own one of these cards and mikec is worried about the process I found it relavent to post this source and since I didn't read a detailed account of this problem and since his only reply is that he is asking nvidia to elaborate it's almost impossible to draw a conclusion based on it.
I posted the link to the thread for the hothardware screens where the nv35's AA is terrible (not blurry) just not nearly as smooth as the radeon's.
