The biggest problem is that the architecture is simply inferior to Sandy Bridge in terms of efficiency. The scheduler fixes were already released but didn't really make a difference. http://www.tomshardware.co.uk/windows-7-hotfix-bulldozer-performance,review-32365.html
One is a Windows scheduler update, the other is a BIOS update for the throttling you mentioned. In other words, don't expect a miracle. It does beat the 2500K in some tasks but not most. It's still going to do everything you ask it to though, so no worries.
