Yes, i agree with Ashish... Im from india too and prices are significantly higher here (unfortunately). I got my GTX 660 Ti for 22K and a GTX 660 is 19K so the only one for 15K is the GTX 650 TI but you can get a Radeon 7850 1GB for 15-16K and the 7850 is a much better performing card than the GTX 650 TI.
Go for the Radeon 7850 1GB model and buy it from any of the following brands-
Yes get the Corsair CX500 V2 version (Corsair fixed all the problems in the V2 version).It seems to be the best at that price. If you want cheaper, buy the Antec Neo Eco 520W but its not the best as it has only 80+ rating not 80+Bronze....
