Can you provide a photo of the card (front/back side close ups if possible)? That would really help.
I did find this via Google based on that "180-P0009-0000-C03" number you gave: http://www.l7inc.us/part_NVIDIATNT2
This is the search link: http://www.google.com/search?hl=en&i...=Google+Search
So, that would make sense for it to be a TNT-class card.
