You cannot buy a gaming laptop below 75K+ than again all those are outdated.A good mobile GFX card itself costs around 30K(970M,980M I am not even talking about SLI).The only viable option here is to with Lenovo Y50-70 (beware don't buy the 860M with TN but the latest 960M IPS).Believe me, extra 10K will be worth it.
Then again if you any relatives outside(US preferable) ask them to buy you one, as it is a lot cheaper.(ASUS, Dell, Lenovo, MSI all provide Global Warranty nowadays)
