First of all if u want to game then dont get a laptop. Secondly i doubt you'll get even a half decent gaming machine at that cost. Not being harsh bro just being honest....
In 30k, you can find laptops which can just about barely play a newly released game.
If you want to stay within 30k budget, buy the Acer 4530. If you can increase budget to around 32k, get the Lenovo G430a(much better than Acer 4530, has a nVidia 9300M graphics)
