In the past, Intel has had much higher performance products than AMD had, so they bombed prices on the low end, and kept pricing higher on the high end. This time, AMD's got as speedy processors as Intel does at the high end. There's nothing Intel can do. They can't bomb prices without hurting themselves.
It doesn't get a lot better than that, especially for a company that just hasn't been doing very well for the last year. It's going to be good for them tomorrow, and that should have a positive affect on a lot of the other chip makers, especially guys that are closely related. It will have generally a positive affect on the overall market.
