Despite being an AMD fan, and a Phenom owner, I couldn't honestly recommend it if you're looking for a good price/performance ratio, and want it only for playing games.
I bought mine because clocking cores independently could help speedup my groups research by not fighting for servers with another 10 groups at school. It's running Linux at the moment.
However, if you're buying this for a good gaming performance, go for Intel *grinds teeth* If you do have specific application, or planning to use it more like a multicore workstation, _AND_ the benchmark shows that Phenom performs well - e.g. Mainconcept H.264 encoder, even UT3 (because those guys did multithread beyond 2 cores), then maybe it's worth it.
But yeah, if you have an existing AM2 board, and a Phenom drop in works, sure...
I do have some strange booting problems in Linux - mind you that's usually after I've tinkered with AOD in Windows.
If you're an AMD fan, wait for B3 or 45nm version.
