How about Shenzhou laptop Jingdun K580 I7 D1?

The A560-i7 D2 is an upgraded version of the A560-i7 D1, so the A560-i7 D1 doesn't need to be considered.

k470-i7 d1；These three need to depend on your use and focus,Focus on carrying K470,Focus on games recommend K580-i7 D1; A560-i7 D2, the 15-inch screen is larger, and it is more comfortable to play games, but it is heavier and inconvenient to carry. k580-i7 d1；A560-i7 D2 These two K580-i7 D1 have better performance, so buy K580 if you pursue game performance; The A560-i7 D2 is more cost-effective, so if you have a limited budget, buy this one.

I'm using a k580 i5480 d3

My book is still quite cost-effective.。

I don't think you need to buy the i7 because the i5 is more technologically mature than the i7 and the performance of the i5 is already very powerful, with a GT445 graphics card, I recommend that you still buy the K580, I bought the 4900

The k580 i3 d3 I bought with the win7 flagship version is very good to use the online 4088 to start.

Hello friends, both of these notebooks use IVY Bridge new architecture i5 3210M processor, size, 2G GDDR3 video memory, 128-bit wide notebook mid-range GT650M graphics card, the main difference is the difference in memory capacity, D1 is equipped with 4G DDR3 1333 memory as standard, while D0 is equipped with 8G DDR3 1333 memory as standard. And** is 100 yuan more expensive, you can understand it by looking at the parameters I listed.

D0 has 4G less RAM, which seems to be cheaper.

The CPU of the Shenzhou Jingdun K570N is replaceable. Normally, replacing the CPU requires first checking the processor models and specifications supported by the motherboard, and then purchasing a new CPU according to the requirements of which CPU models are compatible with the motherboard, and then disassembling the old CPU for cleaning and replacement. It should be noted that when replacing the CPU, the front sock may need to be reinforced with heating reinforcement solid glue to ensure that the CPU can work stably.

Since the replacement of the CPU involves disassembly and assembly and involves hardware work, it is recommended to do so with the help of a professional. In addition, there is a certain risk of replacing the CPU, and if it is not done properly, it may cause damage to the equipment, so it is recommended to carry out it under the guidance of experienced personnel.
