Earlier this year, a won a March Madness contest on this site and for a prize I got a GTX 480 from Mr. Ryan Shrout himself.
I believe it is the one he reviewed, but not positive. It is NVIDIA-branded, with no branding from a partner (EVGA, BFG Tech, etc). I believe these early sample cards for NVIDIA are manufactured by Foxconn.
I have not tested it, but I have no reason to believe it doesn't work. What's something like this worth?
