With current market price, Phenom II 955 n 500 GB HDD is not possible within 11K
the motherboard list that u gave is for AM3 not AM3+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"
sigh...dont know what to say...everything has been said & OP continues to ignore.
tarun...dont start stupid threads if u dont want to listen. buy anything and u will be happy.
to hit 4.0 ghz on phenom II...we are suggesting u a motherboard capable of that first and power supply. processor later.
important things first.
first thing 1st:
1. get a PSU that can support overclocking i.e. a proper PSU. not desi brands.
2. get a motherboard with 6+2 or *+2 VRM & if possible with VRM heatsink
3. get a cooler depending on how much you want to hit 3.8Ghz or more. or just for the safety of your processor as Phenom II coolers are really unreliable.
4. buy Phenom II X4 ***
you miss one step & something will break.
^^TP, I was not talking about only CPU and HDD. Look at Op's need, within 11K, he needs the Ram + Motherboard too within 10K budget.
