This machine is very good. I have never seen this kind of product with all perfect specifications. It’s performance is very pretty. When first time I puchased this I was feeling comfortable no over heat no display pixel problem. Perfet resolution with hd video result. Sound quality is also very good. I like this kind of product refer to my friends. My friends are also good machine liker. They use most good product with my reference. I used it also for my 3d games. I feel better than my old one machine.
