IMO the best value from AMD right now is the 32nm Socket FM1 Llano. Drop that into a Crossfire/SLI motherboard and you would have a very nice gaming setup, particularly if it can hit 4.4ghz. These CPUs seem to be going for a little over $100.
The Phenom II X6 is also a good option, but the 6 cores aren't very useful for gaming. Prices have dropped to around $150 for the CPU which is pretty good.
An Intel 2500K is still the best bet if you're looking for something high end.
I would recommend an i3 if they could be overclocked. Intel doesn't really offer anything useful for gaming for under $200.
