You are correct that no one on this thread has made this claim, however if you read various threads across the web based on the specs the assumption was that they would be twice as fast as their current counter parts. I purchased 2 of the 3870's and I am running them in CF and I am trying to figure out whether I should take them back and get the new 4850/4870 instead. Since there are not any comparison tests yet, I have to speculate on the performance differences between the new cards and the current cards. I have until the end of the month so I still have plenty of time assuming there are no shortages of the cards.
