Alrighty sorry for coming in late Vaibhav, I was busy in Game Suggestion Thread.
Here are some things.
For Processor I guess Intel 3700K is the best option for you.
Now if you want to overclock then ASUS ROG series would be more suited for you because it gives you very stable environment to work upon. I know it because I have used some Motherboards of my friends and I am currently using ROG Mobo myself so I can assure you that the money you put in that would be worth it.
As for HDD I saw some suggestions about WD 2 TB Blue Edition. AFAIK there is no such thing Blue Edition is only till 1 TB after that its either Black Edition which would set you back for 10K or Green Edition which is 5K. If you are not going to get a SSD right now hen going for anything other than Black Edition would be terrible idea.
Now coming to most important GPU part. I think you are better off with a single card and a good Monitor because if you get a CF setup and not so good monitor then you won't have much to look at. Also single card setup has its own benefits, I am not against CF setup but be warned that you'll need a learning curve for some games. Also if you are going for CF setup then 7870 CF setup is more than enough for you considering your budget, though I would suggest you for a single card setup. This is coming from a guy who owns a CF setup himself. I am saying this because when you move to CF setup then you have to amp up other things too like Cabinet, it should be spacey and should have fans in front of the cards to cool them off, specially in summer when temps gets crazy in India. Also with CF setup you'll have to sacrifice on other things like input devices which are most important as per me.
What good is a game when you are playing it with a 800 DPI mouse and a normal keyboard without nice headphone. I mean gaming is not just watching, its about feeling the game, and that can't be complete without proper input devices and output devices.
For Monitor I don't know much but I guess Dell UltraSharp U2312HM would do fine as I have read some nice reviews and some members are also using it and are quite happy with the performance.
As you already said that temps get high at your place so I suggest the Cooler I am using, Noctua NH U12P-SE2 if you can find one, or you can go for Corsair A70 or CM EVO with dual fan setup.
Also as you'll be buying online so keep atleast 2K for shipping alone because the UPS we are talking about will cost you 400 INR just for shipping and with all other components it will more like 1.5-2K. Trust me I know it because I have faced it. I bought my entire RIG online.
The config given by Myth is really good. Just replace GPU with single 7970 and MOBO with a ROG mobo. And then the remaining money will go for input devices as he hasn't mentioned any and the budget he stated already shooted out.
I hope my post is helpful to you. You said me earlier so I specifically came here in your thread to reply.
