With out modification and external costs 30 up to 40K laptops are not near to good gaming laptop experience.... If I'm not wrong now day's you should have at list 65K and above for gaming laptops.... Think about it if you buy 40K laptop you will run some modern games with medium or low quality and then you will buy external ram and other components which is not advised because some issues and device specifications matters.... And yet it will not be enough specially if you are playing high HD graphics games online
