I don't know why you are creating threads on a per day basis.
After hitting 4.0 Ghz, you'll want to hit 5.0 Ghz.
Better THINK logically and *plan* an upgrade over long term if you are short of money...which you obviously are.

Like Joker told you, get the motherboard and PSU now. Gigabyte 990FXA-UD3 + Seasonic S12II 620w. Rs. 9500 + 4400 = Rs. 13900.
Processor (FX-8120) and CPU cooler later. Preferably Hard Disk later too as they are expensive at the moment.
Either have a budget for something good, or don't buy anything at all. This is my recommendation for you because at the moment you are merely going for sidegrade which isn't going to be any/much improvement on currently what you have, and you _will_ regret it. And if you will still continue to ignore the advice given to you over here, there is no point of creating such threads and asking for help from us. Do what you feel like.
Kindly check the motherboards around your price here. See
"high failure rate" mentioned. "no X6, no X4 over 3.5 Ghz"
