Laptop Graphics Card

Hi just need some opinions. Looking for a new laptop.

I basically need something with decent graphics I’ve spotted one but it doesnt have dedicated graphics, it has dynamic graphics. I dont know much about dynamic graphics and was just wondering how good a 256mb dynamic graphics card with 2gb RAM would be.

The laptop will be mainly will be mainly used for gaming including Warcraft 🙂

Anyways any help is very much appreciated 😀
