If you plan to overclock, this is what I'd recommend:
Rs 7 790 AMD 3.5 AM3+ FX 6-Core Edition FX-6300 (FD6300WMHKBOX) Processorhttp://www.flipkart....tmdz2whghfbfxnw
Rs 13 780 Sapphire AMD/ATI HD 7850 1GB GDDR5 1 GB GDDR5 Graphics Cardhttp://www.flipkart....tmddu7g4fbrvzvt
Rs 5 898 Gigabyte GA-970A-DS3P Motherboardhttp://www.flipkart....tmdt9h6w2wsfg2c
Rs 3 999 Seagate Barracuda 1 TB Desktop Internal Hard Drive (ST1000DM003)http://www.flipkart....tmd6uyn8vr4hrma
Rs 2 612 Corsair DDR3 4 GB (1 x 4 GB) PC RAM (CMX4GX3M1A1600C11)http://www.flipkart....tmdd73f2hytmhfj
Rs 3 250 Corsair VS550 550 Watt PSUhttp://www.flipkart....tmdg36xx8yzgjrs
Rs 962 LG GH24NS95/GH24NSB0 DVD Burner Internal Optical Drivehttp://www.flipkart....tmds9ftbrnayxwh
= Rs 38 291
The budget was a bit tight, so the rig does not include the CPU cooler - I figured it's a better idea to buy a faster GPU now and leave the cooler for later. Do not overclock until you buy a better cooler.
The rig does not include a case either, because I couldn't find any on this website (?).
