ATI has more than Nvidia this round where as last round, Nvidia had way more than ATI. It is these filters, lack there of, that cause the X600, R670 and R680 to all tank going from 2x to 4x AA. It only got worse with 8xAA. Nvidia on the other hand left their numbers the same since G80 which is why they killed the R6xx line in AA, but is now losing when you go above 4x.
Well whatever the case may be I love this cards performance at 8XAA.
