Re: Gigabyte 280 GTX @ $460 shipped
The official price drop was to $499 so I don't think you'll see $400 280s until the 55nm parts either come out or are right around the corner. And when the 55nm parts do come out you can bet they won't be cheap. IE, pay $600 for a 55nm 280 or $400 for the older 65nm card.
I like $450 today and dumping it for a minimal loss ($50 - $100) in a month or two if something significantly better comes out. This plan would not have worked @ the old $650 price point......
