2. If it is for study and entertainment, around 3000-4000 is enough. I suggest you buy the i5 processor on the market, which is now the mainstream in the market.

3. If your major is inseparable from computers, such as design, which requires high computer configuration, it is recommended to choose a better graphics card, preferably above 1G, which may be around 5000.

4. Brand: Lenovo and ASUS can be used in China, with high cost performance, and both brands have good heat dissipation. Many series of ASUS pay attention to different features, such as sound effects and graphic processing. Don't choose HP, the heat dissipation is not good and it is easy to crash. I hope I can help you.
