Need help choosing between 2 laptops

Hi:
I'm currently looking for a new laptop. I've narrowed down my choices to 2 laptops, they have the same price.

Laptop 1:
Intel i3 2310M Sandy Bridge
8GB DDR3 1333MHz
15.6" 1366x768
Nvidia GTX 560M 1.5GB GDDR5

Laptop 2:
Intel i7 3610QM Ivy Bridge
8GB DDR3 1333MHz
15.6" 1366x768
Nvidia GT 650M 2GB DDR3

I will use the laptop mainly for gaming, Battlefield 3, Diablo 3, Max Payne 3.. etc..

Which one should I choose? Thanks in advance.
