When the 300 series cards come out, there's going to be so much pent-up demand among people who insist on buying Nvidia, they could come out charging $800. Probably will, too, and they'll still sell out as fast as they can make them. If you're looking for a price war, that'll probably happen in like ... 2011, if ever.
5850 was released at 269.99, thatas what made that card such a winner. Look for it to finally go back to that. Thats still leaves a big gap between it and a 5770. Nvidia might get my cash if something interesting arrives at the 220-250.
That's what the HD5830 is for. I wouldn't get you hopes up on a fermi card in that price range for a while.
See that i what im waiting for. i want the fermi to drop the 5850 back to its regular prices so the 5830 will hit around the 220-230 mark. if it does i will def buy the 5830 if the reviews prove it to be as good as it seems it will be.
