Nvidia Partners Discontinue The GTX275 Page: 1
Bye Bye GTX275, GTX285.
Many of Nvidia's graphics add in board partners have confirmed their decision to cancel their GTX275 and GTX285 based products, due to terrible availability. We're not yet sure if this is a move to keep the market waiting for Fermi, or simple a mistake on Nvidia's behalf, they didn't order enough wafers, meaning the GTX260, 275 and 285 cards' availability was atrocious.
I guess if you're in the market for a new GPU then you have a few options, buy a GT200 card now, buy a 5800 series card or wait for Fermi, whenever it may come.
