1. i5 is going above your budget. If u raise your budget by about 10k then it might add.
2. Those are very vague specs shown. There aren't images showing all parts of the cabinet and how the inside looks. First of all iBall isn't good at anything. I don't think that has good air flow design. May not have cable management. The one i suggested has front USB 3.0 ports. PSU location unknown. It looks more show-off than actual functionality
3. ASUS r9 270x has 2 models and that is not the better TOP version. Between the MSI GTX 660 OC and ASUS r9 270x, both are good at their price points - there is no deal here. I haven't personally bought from amazon.com so no idea there. If u do please tell the experience and amount u paid in total
MONITOR: Try and get any monitor with 2ms or less response time and g - sync monitors are hard to get in India even though they are very good i sugesst going for ASUS 9000 rs or below 21.51 inch.
GPU: Gigabyte GTX 770 2GB GDDR5 OC. This card will be shipped from America look and Read the shipping details properly probs around 600 rs for long time delivery 11 - 17 days. RS. 22319 BTW THIS IS A DEAL OF A LIFETIME OR GET A RADEON CARD.
Motherboard: ASUS M5A 97 R2.0 RS 7250 THIS MOTHERBOARD GOES INSANELY WELL WITH THIS CPU! amd cool n quiet technology helps auto overclocking, this makes the processor go up to the power of the i5 4430! plus it has 6 cores playing later games will be way better and amd is going to all the most advanced gaming engines and telling them to make the games for AMD CPUS.
