Pros: The Microsoft hotfixes address Windows 7 inability to utilize FX Bulldozer multi-threading architecture. It is not a flaw in AMD's Bulldozer series, but in Microsoft's OS inability to efficiently use the Bulldozer architecture.
Cons: The two hotfixes listed below are NOT available through Microsoft's critical/optional updates; however are available via Microsoft websites/sent via e-mail.
Pros: In true AMD fashion - great CPU for the money and just fine for gaming or multitasking. Good overclocker, relatively cool. Most i5 models will beat it at benchmarks, but when it comes to real use, it performs great in every application and is half the price.
Cons: None really. The Vishera line of AM3+'s are a bit more efficient than the Zambezi's. But dollar for dollar, this is a great CPU.
