Which one is a better gaming laptop?

I was planning to buy a new laptop mainly for gaming and entertainment and some project work but my main concern is gaming. I have been searching the net for around a month and finally came across 2 laptops which suited my budget. My budget was 47k-55k INR. The 2 laptops are:
1. HP Pavilion 15 P045TX: core i7 4510U 2.0ghz upto 3.1 ghz by turbo boost, 8gb ddr3 ram, 1tb hard disk and 2gb Nvidia 840m ddr3
2.Lenovo z500: core i5 3230m 2.6 ghz upto 3.2ghz by turbo boost, 6gb ram ddr3, 1tb hard disk and 2gb Nvidia 740m ddr3

The first laptop is of 55k and the second one of 48k. I wanted to play high end games like Far cry 4, Battlefield 4, NFS rivals, GTA 5 at a decent fps. So which would be a better laptop for gaming at 1366-768 resolution. And if you have another laptop with better specs for gaming, please do suggest me. It should be in my budget i.e. 47k-55k INR. I only have a week left. Please reply As soon as possible.

I've never had any luck with Pavilions, my last one got extremly hot and killed the battery, i'm not joking when i say this, i've cooked toaster pancakes on the botto of it.

Better go for HP 4th Generation processor will generate less heat and also it has high power processor. Graphics card in HP is better than Lenovo. For high graphics games go for HP Pavilion 15 P045TX.
