HP dv6-6171tx. Best thing about it is the graphics card. The most powerful a laptop could have AMD 6770. Price should be around 1k usd or less
i7 is added too
I recommend purchasing the Samsung RC520, I've got it myself. The high battery of life of 7 to 8 hours makes the device very portable and you are unlikely to need mains power when you are out and about. Even relatively new games function well on this machine.
Unless it HAS to be a laptop, you should probably consider a desktop. They are better for gaming and tend to be easier to upgrade and have better airflow.
There's many variations of that laptop (if you go to newegg, laptops, and select Asus.) for anywhere from $1000 - $2000 so you can pretty much pick which ever fits you best for your budget. But honestly, I have the 17.6" version of that laptop and I have no problem playing games on it.
The thing is I want to take it with me because my parents are very strict ad take anything I buy/that they give me when I get in trouble so I want to be able to take it with me when I'm not at home.
How? I have one just like that and I carry it back and forth to class six times a week. It's big and bulky, but there is a 15 inch version that is definitely smaller. Basically, if you know how to take care of your toys you have nothing to worry about.
