Caporegime
The motherboard the OP has won't run the HT of an Athlon II or a Phenom II at full speed:

Also, a 125W CPU maybe pushing the limits of the motherboard. I would suggest getting a Phenom II X4 945 as this has a 95W TDP.
I would also look at getting a KFA2 GTX460 Green Edition as this only require a single PCI-E power connector:

The CX400W is actually quite a decent PSU and is actually capable of delivering 450W :

The new CX430W is actually considered an inferior PSU.
With a 95W Phenom II X4 and a GTX460 768MB Green Edition you should be able to keep your existing PSU.
