Forgot to mention few things
1) I need only CPU. I have Moniter, Keyboard, Mouse
2) Approx date of purchase - from 1 week to 1 month
3) Budget around 30-35k INR( 537$ to 626$)
4) Preferred Website(s) for Parts: flipkart.com
5) Location: Bangalore
6) Overclocking - May be in future
7) Reason for new one - My current system is very old and slow.
Am not much worried about gaming performance as much as processor performance. The motherboard selected does not have on-board graphics. So I chose a graphics card that was cheap and good enough to play NFS Undercover range games may be. I am ok with on-board graphics card. But I didn't find motherboard with USB 3.0 support and good graphics card. I will also be using GIMP(Photoshop equivalent)
I may start use CPU intensive operations like compiling big projects. And I heard AMD Processors heat up a lot. So I added a cooler.
SMPS - I don't have least idea on power consumption other than above Graphics card needs minimum of 300 Watt. So I planning to go with minimum required + 50 watt to be future ready.
