My budget is between 15k- 20K. Confused between these phones - Sony Xperia C, Lenovo P780, MotoX.Please advise?

I'm planning to buy new smartphone. My budget is between 15k- 20K. Please advise me a good phone having awesome speed, can play full HD videos, multitasking, good camera quality, and smooth touch screen. I understand its not easy to get all this in 15k - 20k, however I want you to do some research for me. Also please advise that which processor is better in terms of speed. MediaTek or Qualcomm? I did a lot research and confused between these phones - Sony Xperia C, Lenovo P780, Moto X ( coming soon). Or Please advise if you know any other good phone.

Looking forward for your reply.

The Xperia C is equipped with 1.2 GHz quad-core processor with 1 GB RAM, which accomplishes multiple tasks. Play high grade games that have great graphics as the Xperia C has a PowerVR SGX544 graphics chip; so the game never ends, it only gets better. Store all the multimedia that is important to your work on the 4 GB internal memory that is expandable up to 32 GB.

An imaging technology like HDR (High Dynamic Range) allows you to capture crystal clear pictures, with natural colours, against a strong backlight.

Go for spice mi 525 full hd at rs10k and save your money.

MOTO X will destroy all other phones in this range. Wait for it to be launched in India.
