Amd phenom z 940 3ghz (125w)

Hello. I have an amd phenom II x4 z 940 3ghz on an MSI KA780G. the problem is my mobo, it crashed.
So i have to get a new one. the point is is i can't find a lot of am2+ that support 125w cpu. can i use other socket mobos (am3 or am2+ with less power) with any bios upgrade? any suggestions?

I would suggest you get a cheaper am3+ motherboard and some cheap DDR3.
This leaves you with an upgrade path as the new AMD cpu's all currently use the AM3+ socket.

Heres some decent lower end boards. Please double check the cpu support list as all I did was check for 125w support and not your specific processor.
