400 yuan had better not exceed the price difference of notebooks of around 4,000 yuan. .

The heat dissipation of 3000-4000 machines may not be the best, but the biggest concern of this book is the heat dissipation.

A card is really better than N card in drawing. If you want to play games, you should choose N card.

1. Lenovo G450A-TFO(S) constellation version, the price is 4 199. It completely meets your requirements. This is very popular recently. Of course, Lenovo Y450A has a better configuration, but the price is around 5 100.

3. In addition, Acer ACER 4736ZG is recommended, which is more fashionable in appearance than G450A and costs about 4,000 yuan. The graphics card configuration is G 105M, and the rest are basically the same. Hehe, I want to start with Acer, which looks better.

Sony and Samsung's netbooks are beautiful, but they are not suitable for use. Only suitable for watching. Think about it, after watching a movie, it will burn to more than 60 degrees in a few hours. Can you stand it? Can your love stand it? And when you want to open more software, you will experience the difference between driving a car and driving a battery car!

Personally, netbooks are strongly discouraged.
