If you don't know computers, you'd better not buy them on Taobao.
The reasons are as follows
1, the motherboard sold on Taobao may be refurbished; The memory sold may be fake (the real fake memory capacity is as different as the quality), and the hard disk may not be new.
2. Because I don't know computers, I can't deal with minor computer problems, such as common poisoning, crashes or others, but if I buy them in a physical store, I can go directly to the store with my computer!
A mainframe 1000 yuan is a bit low, so it's ok if you don't play super-large games. (However, there is a great possibility that the mainframe will be refurbished. ) If you like playing games, especially .3d large-scale games, then you need to install a discrete graphics card, and the power supply, memory, CPU and so on should be correspondingly higher. Then, 1000 is not enough!
Personally, I suggest that CPU choose intel instead of AMD.
