for anyone interested how to find out how many phase your vrm has , I found this
explanation which should be straight forward .
is the vrm voltage same as the motherboard voltage on hardware monitor?
in another word how can I monitor its temp and what is considered hot ? above 70?
if as per my previous notes anyone could suggest a good gpu that will be much appreciated

It is not difficult to tell how many phases there are on a motherboard, for those who are curious. Look at the big black squares, called chokes (They're inductors, boxes containing coils that basically help filter and limit the current). If you see 10... that usually means an 8+2. 5... usually a 4+1. Sometimes there are different combinations depending on the platform. Note that amount of chokes will not necessarily mean that you have that amount of phases (due to such things as split phasing, defined by the PWM controller), however a split 4+1 phase with 10 chokes (split 8+2 power system) is still capable of handling more current than a split 4+1 phase with 5 chokes.
Also, a list of all AMD motherboards with detailed VRM information including quality/amount of phases can be found here."
