Peformance difference between two laptops.

Hi guys! I'm looking for some advice on laptops, and i think i may have found the one, however, their are a few different models of it. I was hoping you guys could help me and tell me just about how much of a performance difference i would see between the two.

The main uses for my laptop would be word processing, programming C++, internet surfing, watching videos, and light gaming (Things like TF2, mass effect, limbo, etc)

Here are the specs of the laptops.
