Seller knows it's a PPC card but the PPC fails and thus work just like a MK3 and thus he sells it as such. He might think the card is going downhill or it already has and that's why it's sold AS-IS.
As always when seller sais sold untested of as-is my warninglights goes off. Especialy when so much other data is precent. Be prepared to get a dead or dying board.
