In my suggestion, you should try to invest more on core components (CPU,GPU,RAM) rather than other accesories.
Your budget will only bring you to entry level gaming, but still you'll be able to play present titles, atleast on full HD.
Here are the specs and prices : (Flipkart)
CPU : Intel i5-4440, 3.2 GHz Quad Core , Rs. 12,000
GPU : XFX R9-260x Double Dissipation(DD), Rs. 11,000
RAM : Cosair Vengeance 8GB, 1600MHz (4x2), Rs. 6000
Motherboard: ASRock H87 Extreme 4, Rs.7000
PSU : Corsair VS 550, Rs. 3400
HDD : WD Caviar Blue 500 GB, Rs. 3000
This is a little over your budget, but I promise you won't be disappointed.
