An ati hd 3470 costs now around 15 € with shipping. If you like try to sell it, a Win user might buy it. I have got a hd 4550 card as well, but i do not freak out when there is no driver update for it, then i just use a different card. pci-e cards are so easy to change, i need less than 1 min to do so, must be very hard for you to buy something that works I would not cry for a card with that value.
