I'm considering putting together a new system later this year (if finances permit) and looking at the AMD 955/965 BE processors. I was reading a review of the 965 BE on Newegg.com and in a review was something I've totally missed all along...

Are all AM3 processors backwards compatible to AM2 motherboards? If that's the case, I really can piecemeal my system together as money becomes available... I'm running an Abit Fatal1ty AM2 motherboard now with an Athlon 64 X2 6000+ and one reviewer said he dropped a 965 BE and got 4x the system speed, and even more when he switched to an AM3 motherboard...

Basic question repeated... Are all AM3 processoers backwards compatible to all AM2 and AM2+ motherboards?
(I know you don't get all the features, but they do work, and work correctly?)

yes all am3 cpu's are backwards compatible with most am2+ and some am2 boards

you dont lose much by using it on an older board you can look around there are a lot of reviews comparing the am3 cpu's using ddr2 and ddr3 ram and the loss is so minimal its hardly notable

The next logical question them would be can my older (Abit Fatal1ty An9 32x) motherboard handle a 125W CPU?

That's because there won't have been any since around May 2008.

The Athlon X2 6000 is a 125W cpu if you have the 3.0Ghz Windsor core varient, so wattage isn't the problem. Your problem is that you need proper bios support through bios updates, and many older AM2/AM2+ boards haven't gotten the updates for new AM3 processors.

Alright, that's the info I was looking for, looks like it probably isn't going to be do-able... So I'll keep looking at the 955 or 965 BE with the MSI 790FX-GD70 at the moment...

Thoughts on that appreciated, but not releveant to this thread...
