It's not possible to fit a z77 mobo and a Graphics card in about 14000 bucks.
Cheapest Z77 board i could find: http://hardwire.in/motherboards-/443-gigabyte-z77m-d3h-intel-motherboard.html
I would not recommend a graphics card below HD7770 for even casual gaming with that display but I may be wrong here.
Other posters, please use the site that I have linked above or this: http://www.theitdepot.com/
since OP will probably be buying in India.
