Answers & Comments
I don't have this card but I am very interested in buying it so I have been tracking reviews and so far I have heard a lot of problems with this card. Some things to check. What version of OS X are you running? I have heard many complaints about the card's performance after upgrading to OS X 6.6. If you have 6.6 you should reinstall the drivers and sometimes that helps. I would go to both apple.com and nvidia.com to make sure you have the best and most recent drivers. Good luck.
