Sounds to me like someone sold you a PC version card.
It does say the words "Mac Edition" like it should on the outside of the card and it still displays everything properly. Seems like an awful lot of trouble to put a PC card inside of a case for a Mac card! What do you think points to the fact that it is PC? My computer recognizes it fine. Also it's strange to me that it gets funky right when I launch the app rather than simply crashing the app during usage.
>bad drivers (should be the most recent!)
Well... what is the driver version number, and have you checked at the nVidia site?

John may have a better answer than mine. Mine was based on the fact that if you boot up with a PC card you do not get the normal Mac UEFI boot up screen.
What version of OSX do you have?

Which is what I had, although I reinstalled it to be safe. I ran into the video trouble AGAIN while just trying to stream a video online! I think it's safe to say it's just a bad card. Is there any other kind of diagnostic I could run or check before I totally give up on it?
Thanks so much for all the help!
In an attempt to exhaust all of the problems with the card, I also tried playing a video game through Steam (which is half of the reason people upgrade their graphics cards anyway!) and it caused the same screen issue. Despite the normal system display that the card provides, it seems I have a dud when it comes to anything graphics-intensive. Time to talk to the seller....
