Many answered no there aren't any and I respect your answer but searching in google I found this

Is it true or not/
yeah that one is real alright, but it was only a prototype. Guess some engineers got bored and made one during their lunch brake or something.
It didn't get into production stage however, and frankly it is easy to understand why they didn't bother to develop the card any further with crossfire drivers being like they were those days...
3 gpu cards dont make any more sense these days either
ps use quick edit, it works for me at least...
