500+ BE at Tiger direct Also check out Compusa website. The egg is currently out of stock. use www.pricegrabber.com
I prefer newegg over tigerdirect, but tigerdirect is not horrible.
My wife has an x2 6000+. The dang thing flies with its 8800 GTX> It's just not as energy efficient. The egg has the for 114.99 and they are 3ghz stock. Not sure on the overclock, but I bet you could get 3.2
If all else fails, Get a Phenom
