To be honest with you 4th Gen CPU known as Haswell does not have a significant boost from 3rd Gen Cpu known as Ivy Bridge. Do you really want to waste money on something that will gain you 5-10% of performance? Plus you're only gaming so it won't really matter. Plus you live in India and its really hot there, if you didn't know Haswell gets extremely hot just like Ivy Bridge did but worse since it consumes more wattage and has its own VRM. So with your ambient temperature and Haswell temperature you will be creating a miniature sun right in your bedroom.
