What laptop should i get? Can't decide?

I wanna get a new laptop to replace my old desktop i got back in 05.
I most use it for web surfing, music, email ect, But the biggest load is the fact that i want to play Leauge of legends, and minecraft. And id like to skype, and play a few MMO's, i just want a laptop thats decent in most of that, i don't really mind lag i just don't want anything that crashes, i mean… 2005 windows XP. Yeah.
Anything is faster

Consider Dell Inspiron i7559-763BLK 15.6" Full-HD Gaming Laptop

It's got NVIDIA GeForce GTX960M graphics card that will play Leauge of legends, Minecraft and many more modern games at high to ultra settings
