Which gaming laptop is better? - 1

So i have been looking for a gaming laptop that i can just play casually, nothing high end just enough to play swtor, wow, and guildwars 2 at a medium/ high settings with smooth gameplay. I have brought it down to these two laptops

The lenovo y40

and the MSi gp70 leopard

I was kinda set on the msi until i saw this lenovo but i'm not sure which one is better. The lenovo has i7 core while msi has an i5, but i don't know how the AMD graphics are or if there better/at par with the msi

Your help will be great

AMD graphics
