How Do I Choose the Best Desktop Computer?

A desktop computer is an independent phase-separated computer that is completely unconnected with other components. Compared to laptops and netbooks, it is relatively large. The host, monitor, and other devices are generally relatively independent. On the workbench. Hence the name desktop.

Difference between brand machine and assembly machine

Desktop Appearance and Features

The appearance of most brands is fashionable and the colors are gorgeous. The most representative should be IBM and Dell. Their desktops are mostly black, dignified and generous, giving people a sense of high taste. Such as the Shenzhou New Dream series gives a refreshing feeling, very coordinated. The assembly machine can choose very few sets, and the overall view is not very coordinated. In terms of functions, brand machines are more prominent, and some are equipped with functions such as one-click recovery, encryption protection, keyboard overclocking, etc., which are very convenient to use. Assembly machines are difficult to implement. However, there are a lot of personalized suits on the market, and there are a lot of functions. You can usually pay attention to them.

Desktop Service

Brand machines generally have several free after-sales service and technical service hotlines. For users, it provides convenient conditions for communicating with manufacturers. Lenovo, Shenzhou, etc. also provide a nationwide warranty. In contrast, assembly machines can only have a limited warranty at the seller, and there are occasions when three obstacles and four obstacles occur. However, after fierce competition in the market, the after-sales service of the assembly machine has also been greatly improved, but compared to the three-year main parts warranty of the brand machine, the warranty time of the assembly machine is still shorter.

Desktop hard drive memory

At the same price, the hard disk capacity and memory of the brand machine is much less than that of the assembly machine, which is about half that of the assembly machine. In addition, in the case of unmarked hard drives of the brand machine, in all cases, it is 5400 rpm, which seriously affects the performance of the system. For machines with integrated graphics, it is necessary to borrow the main memory. Such a small memory (128m) computer performance is conceivable. So whether it is a brand machine or an assembly machine, it is recommended to buy an independent graphics card machine. There is really not enough money to buy a model with an upgradeable graphics card with an AGP slot. The hard disk and memory of the assembly machine can be customized according to their own funds. In the brand machine, P4C with DDR266 memory is really a big horse cart. Insufficient bandwidth will also affect the overall performance. Equipped with DDR400 or even dual-channel DDR400 memory.

Desktop Graphics Motherboard

The graphics card is a big flaw in the brand. In order to pursue maximum profits, manufacturers often work hard on graphics cards. For example, P4 models around 4,000 yuan, most brand-name machines are integrated graphics, and compatible machines can even be equipped with REDON9600PRO128M graphics cards. The difference between them can be said that one is in the sky and the other is underground. In the days when DX9 games became popular, some branded machines also used GF5200 to support DX9 graphics cards, but most of them were malformed graphics cards with 64-bit video memory. How much faster could it be than GF2MX400! It is difficult for a novice to use graphics cards with 128-bit and 64-bit memory bandwidth. Many of them are not marked in the advertisements, even including famous brands. The motherboard is also a problem for brand machines. In order to reduce costs, they will use motherboards such as VIASIS chips. It is not that these motherboards are not good. Compared with INTER chip motherboards, the performance difference is self-evident, but the compatibility is poor. Many, you can pay attention to the motherboard when buying brand machines, try to buy motherboards with INTER chips. (Except AMD models)

5. Display, chassis, etc.

The comparability of the above categories of articles is poor, so we will not analyze them one by one. However, the optical drive and display need to be mentioned again. Needless to say, high-bandwidth displays are more comfortable for the eyes. For example, P4 models under the price of 5,000 yuan, most brands are only equipped with 52xcD-ROM, and a few are equipped with a DVD drive. In the Internet era and a society with a lot of information, it is still necessary to use Kangbao to watch DVDs and back up data.

Summary: If you have sufficient funds, it is best to buy a high-profile brand machine. After all, brand machines are better than assembly machines in terms of product quality, compatibility, after-sales service, appearance and function. When the funds are insufficient and you care about the performance of the machine, buying an assembly machine may be a wise choice.
