Those are all good choices. The Phenom II X4 955BE, while getting a bit long in the tooth, is still a powerful quad core for gaming. And it can be easily OC'd by upping the multiplier if you do nothing else. I had a Phenom II X2 555BE that I was able to unlock to a Phenom II X4 955. And was able to get it to a stable 3.6GHZ by doing nothing more than upping the multiplier. Didn't even have to mess with the voltage.
