The Tech Report posted a story that AMD has decided to slash prices in response to the latest GeForce

We noted in our GeForce GTX 660 Ti review that Nvidia had the advantage in terms of overall gaming performance per dollar. That was no great surprise, since new graphics cards are often priced to make a splash versus the competition. However, we sort of figured AMD had already played its hand by adding a Boost-enabled BIOS to the Radeon HD 7950 that, er, boosts performance. Turns out that adjustment alone wasn't sufficient to win the value sweeps, so AMD has decided to counter the GTX 660 Ti with price cuts across the middle of its lineup.

AMD tells us we can expect to see new prices "towards the end of this week" on several of its products.
Here's the skinny:

The Radeon HD 7950 (including those with Boost) drops from $349 to $319.
The Radeon HD 7870 GHz Edition drops from $299 to $249.
The Radeon HD 7850 2GB drops to $209, and the 1GB version to $189.
