Sadly it failed to meet any of my expectations.
1. It's slower than intel procs that are $80 cheaper
2. It consumes more power than intel procs of the same class
3. It's not a complete revamp of AMD's processor line, just a small revision.
There is honestly no reason to buy one what-so-ever. It's slower, more expensive, and generates more heat.
I am deeply disappointed in AMD tbh, I was really hoping they would step up their game and show intel whats what. Instead they just gave me the Phenom II X8.
Here be a review:
