A post on Tweak3D.net (thanks Game Forces) clarifies the deal with those auctions mentioned yesterday (story), and it seems my skepticism was unfounded, and that this eBay auction, this Yahoo auction, and this Excite Auction (as of this writing, neither of the last two seem to be active yet) are all legit. Apparently the GeForce cards are being auctioned for charity by NVIDIA, and the cards being auctioned will actually be autographed of all things.
