The AMD Phenom 9500 (2.20 GHz) will sell for only $248 (169), while the Phenom 9600 (2.3 GHz) comes with a price tag of $279 (190).
Taking a look at online stores reveals that the asking price there is about $118 higher than AMD's recommended price. However, bearing in mind that these same stores also still list the Phenom 9700 with 2.40 GHz - which has been pushed back to 2008 - we can expect to see prices drop rather quickly.
For reference, Intel sells its smallest quad-core CPU, the Intel Core 2 Q6600, which is also rated at a TDP of 95 W, for around $323. These prices are for the box versions.
