the Mother board is
GA-MA78G-DS3H rev 1.0
AM2+

http://www.gigabyte.com/support-downloads/cpu-support-popup.aspx?pid=2800

now the gigabyte site says nothing above TDP of 95w pretty much

http://www.cpu-upgrade.com/mb-Gigabyte/GA-MA78G-DS3H(rev._1.0).html

This website says it can support a few more some 125w TDP models, who do I trust since the mobo is quite old gigabyte might not of updated its list since rev 2.0

.
You already answered your own question. The manufacturer always has the final say in any specification issues.

A quick internet search on Gigabyte website for "supported CPU" for rev. 1.0 board shows very clearly support for 95W maximum CPU power requirements. (note: the search led me to the same gigabyte website page you referenced
http://www.gigabyte.us/support-downloads/cpu-support-popup.aspx?pid=2800)

Rev 2.x boards extend support up to 125W CPUs


This is probably the reason why...

The power rating does NOT just apply to heat generation that is handled by the CPU heatsink. It also applies to how much CPU power the circuitry (voltage regulators, sockets, "lands", resistors, etc) on the motherboard can handle without damage or reduced performance. The "Rev 2.x" board designs likely increased the power handling capacity of some of the "lands" and/or the components that support powering the CPU.

Analogies:
Motherboard "Land" analogy: you can't light a 100W light bulb that requires using an 20gauge wire by instead using a 32gauge wire. The 32gauge wire will vaporize and/or melt, (note: the higher the gauge number, the thinner the wire). Just like you can't use a 1/4-Watt resistor/chip where a 10-Watt resistor/chip is required. The 1/4-W resistor/chip will not be able to handle the power and will likely literally explode if forced to try to handle 10W of power.
Voltage Regulator analogy:
you can't run a printer that requires a 3 Amp output power adapter by using a 1 Amp power adapter. The internal circuitry of the 1 Amp adapter will either be destroyed or its output voltage will decrease to the point where the printer will not operate.

this guy thought he was running a 125w x2 6000+, now thats not on gigabytes list but is on

http://www.cpu-upgrade.com/mb-Gigabyte/GA-MA78G-DS3H(rev._1.0).html

's list

phenom II 95w are hard to get at the moment
