Well... A guy has been selling that card on falconfly.de forum for a while, and the price was pretty high...

But he didn't sell the card yet. So dont get too exited. 😉 That card is rare, thats a fact. It's single slot SLI, thats also a fact, but in the end, its just V2 SLI, which can be assembled for 2e (1e each card) ex. shipping over ebay. There are those that would pay a bit more for it... But the ones to pay more then 300 EUR for it are even rarer then the card itself 😜
Anyway, if I would suggest you to put the card on ebay and make a bloody good commercial out of it - go to 3dfx communities and tell them about the auction. That way a lot of people can get a chance to get the card, and you might get a fair price for it.
