@Thread opener, since you need a laptop which is jack of all but master of none, I can recommend you Dell Inspiron 15 5000, i7 ULV model. The GPU in it is capable of low to medium quality gaming and screen is good, the build quality is better than most of the Lenovo laptops you get at that price range. You can also jump for HP Envy, but they too have TN panels, which are not that great, and Y50 is a good option, except for terrible screen and some flaws in build.
And if you can stretch your budget to 80K, you can get a good screen, a good processor, and entry level gaming grade GPU in Asus-G551, which has been recently launched and offers good price to performance ratio, better than Y50 if we consider that IPS panel.
