Okay, my bad. I haven't been clear in my post. Lets straighten things out.
I have a friend, who said, if I average 90% or more in my upcoming board exams, he'll gift me those. He also told that he's giving me a budget of 50k..so well, it isn't my money. It's not that I'm wasting his money, but with a mouse like razer ouroborous, who wouldn't want to show off. I chose sv2 frost blue, but then after hearing some personal experiences from my friends, I've heard that its very delicate and has a life of just a year, hence making me do the tough job of searching for another headset. About the sennheiser hd202, no doubt it is an excellent headset, but then, it doesn't carry a mic with it. Me, being a gamer, would want a mic, so well yeah.
About the graphics card, my HD 6850 has gone for RMA and they told me I'll be getting a 7850 2 GB as a replacement.
As for the ram and ssd, I've to think about it but then my friends deal stands only for mouse keyboard and headsets.

I think this pretty much explains the facts.
