Since the thread has obviously derailed into PSU arguments, let me help you.
After reading all the reviews on BD, I'd say you're better just keeping what you have, or selling the Mobo+CPU and picking up a 2500k+Mobo. Guaranteed to alleviate your issues.
Waiting on the next Bulldozer iteration will probably not be in your best interest, and judging from AMD's LOOOOOONG track record of providing lackluster performing chips, it's safe to assume the next one won't be anything special.
Also, the 2500k is CHEAPER than the 8150FX and P67 Mobos can be had for $200 or less that will net you 4GHz+ easily!
Your choice, but I think it's pretty clear cut.
Good luck man!
