If you want to buy a home desktop computer, you don t understand the computer, what are the main pro

What do you need to pay attention to when buying a laptop?

Lenovo, there are many appearance styles, and the most important thing is good after-sales.

If you don't understand, it's better to buy a brand machine.

1.In the same case, the performance of the brand machine is not as good as the performance of the assembly machine, and the brand machine is more about the appearance, and the assembly machine is more about the performance. (Recommended assembly machine).

2.At present, the host is divided into two series, which are AMD and Intel-type processors, most gamers choose AMD because of AMD's overclocking and other functions are stronger, cheaper, etc., but the power consumption is larger, the stability is low, and fewer advanced players like to use Intel because Intel is stable, low power consumption, powerful performance, etc., **high.

3.There are two kinds of graphics cards, one is the NVIDIA type and the other is the ATI type, NVIDIA cards are generally used for games, and the graphics processing of ATI cards is better.

4.The motherboard is also divided into two types, one is for the Intel chipset.

The other one designed with a pin board is a slot board designed for AMD chipsets.

5.There are currently 3 types of memory, namely DDR DDR2 DDR3, and the corresponding memory is selected according to the model of the motherboard.

6.Hard disks are divided into serial ports and parallel ports.

Nowadays, most of them are serial ports, because the transmission speed is faster, the cache of the hard disk is divided into 8M, 16M, 32M, and 64M, and the larger the cache, the faster the extraction speed.

7.The voltage of the power supply provides the foundation of the chassis power supply, so the selection of the power supply should exceed the total power consumption as much as possible, so as to avoid the occurrence of abnormal phenomena such as burn-in or automatic shutdown caused by insufficient power supply.

8.There is no doubt that the vast majority of people choose the optical drive, and if you need to burn, you can choose one with the burning function.

9.The choice of display depends on whether the main screen has bright spots and other issues, and it is recommended that large brands have higher reputation, better quality, and convenient after-sales.

10.For the chassis, speakers, mice and other parts belong to personal collocation, do not recommend.

I hope the above will be of some help to you, and the specific parts and models can be viewed on Zhongguancun computer network.

Note: The closer the frequency between the CPU, motherboard, and memory, the greater the performance.

First of all, don't buy outdated stuff! For example, AMD's latest CPU is either a bulldozer with AM3+ interface or an APU, of course, Phenom II and Athlon-II can also be considered, and those older than this should not be considered! Intel's just depends on the pins, 1155's can be, everything else is outdated!

Don't buy the 1156 either, it's the first generation Core i series, it's not recommended to buy!

If you have a motherboard, try to choose ASUS, MSI, and Gigabyte, the three first-tier manufacturers, if you don't have money, ASRock, Onda, these second-tier ones are OK, and don't buy the lower-end ones!

If the memory is a brand of goods, ** on the line! Such as Apacer, Kingston, ADATA, G.SKILL, Corsair, and Samsung are all branded!

Power supply, such as Zhenhua, Kangshu, Great Wall, Huntkey, Antek, Corsair, Yinxin, Cooler Master are good, if you don't have a separate display, the big buffalo, Jin Hetian can be considered!

Monitors, Samsung, LG, AOCDell, Philips, and Acer are all OK!

In the final analysis, you don't understand hardware, even if the accessories are all first-class licensed goods, all are first-line, they can only be guaranteed in quality, as for performance, cost performance is not guaranteed, people must pick the most profitable for you!

Personally, it is better to buy a desktop machine, and now the popularity of the installation is very wide, and all the hardware is transparent, and you can query the specific parameters, performance and ** on the Internet. You can refer to the online ** and performance selection hardware to buy online in the physical store to help assemble, up to 100 installation costs. If you are not sure about the authenticity of the Internet, you can choose to inquire about the ** and model online, and let them purchase it in the physical store, one guarantees the authenticity, and the other guarantees the after-sales.

Personally, it is recommended not to buy a brand machine, for two reasons, first, the early stage of after-sales is very convenient and free, but the later after-sales delay is long, and the procedures are troublesome, and the later ** is very high. Second, the relative performance configuration of the relative installed machine will be more than 1000 higher, after all, people have brand profits. Saying all that, I don't know if it can help you. Hehe.

The first thing to pay attention to is the key components that affect the speed of the computer...

Hard disk, CPU, motherboard, memory.

They are joined together like water pipes, and where one is thin, the whole stream of water is thin.

So be sure to get the most out of it.

If the CPU supports GPU or APU, then you can save the graphics card, you need a motherboard that can play CPU performance or close, do not integrate the graphics card with the output of the graphics card, according to the main frequency of the motherboard to support the memory to choose the appropriate memory, hard disk, try not to high-speed ,,, because the general is enough, the higher the speed, the better the reading ability, but the heating, the hard disk life will also accelerate aging.

The above is about performance and hardware.

The model of the hardware It is best to test the hardware model after installing the machine. The easiest test is with Master Lu.
