To buy a computer like that

When you need a new computer, there are too many factors to consider from configuration to software and peripheral devices. Therefore, deciding which computer to buy can be a real challenge.

Learn real needs

Most consumers buy computers for web browsing, sending and receiving emails, word processing or spreadsheets. Today, high-end and low-end computers are capable of meeting those essential tasks. Therefore, you should spend a lot of time figuring out your own needs.

Popular computers are now manufactured and assembled with the ability to upgrade hardware configurations, whether it is 4GB of RAM or Blu-ray optical drives to watch high-definition movies (HD DVD ). Therefore, you should not worry that your basic configuration computer will soon become obsolete or have to be replaced when your needs change.

If there is a greater demand, such as video image editing or managing a massive database, then a high-end system with a dual-core processor with a professional graphics card is chosen. priority choice.

The computer game market is also on the rise. Gamers in the group of few goodwill bought the PC tens of millions of VND. The system ensures maximum performance, such as CPU overclocking and dual graphics card setup. In general, the configuration of this model is not higher than that of video processing computers, but gaming computer systems are being improved quickly by manufacturers.

Key factors

The bigger the RAM memory, the better the performance of the application. For Vista-based computers, the RAM capacity should not be less than 1GB. Test results showed that Photoshop nearly doubled with Vista computers with 512MB of RAM.

New generation motherboards can also meet advanced technologies, enhance computer system speed, like second generation SATA connectors for 3 gigabits / second hard drive data exchange ( Gbps), 1 Gb network connection, high definition audio, dual graphics card (SLI or CrossFire). The motherboards with AM2 sockets are for AMD processors.

The front USB port of the camera is convenient for the need to use a digital player, while the rear ports are for external hard drives or printers. High-end new models such as the Media Center PC also have audio and video outputs along with FireWire peripheral ports located in easy-to-use locations.

A well-designed case also makes your day-to-day work on your computer easier and can also help keep the system upgrade maintenance simple, especially at Offices have multiple computer systems for different uses. A well-designed case will not need tools to access the interior, the hard drive installation tray has an easy-to-slide-out structure, the connecting cables carry distinctive color codes for the first part. internal and external termites.

Wear a variety of designs, but the most popular are ATX cases, with connectors located on the back of the body. Recently, a new type of case has been predicted that is capable of replacing the ATX which is BTX. This is an Intel-backed case developed for basic design changes in functionality, providing better heat dissipation.

In case there is a need to upgrade in the future, the type of case that fits the motherboard for two hard drive compartments and a standard PCI slot for additional cards is of interest.

With graphic display on the screen, the graphics card is a PC subsystem that exists in both disassembled expansion board and chip integrated with the motherboard. If you're a veteran gamer, you should buy a discrete graphics card. Low-cost computers usually only have built-in graphics chips, but if it is a motherboard with an expansion PCI slot, upgrading a graphics card is easy.

For multimedia applications that require faster image processing, a minimum of 128MB graphics card is compatible with Vista's 3D Aero acceleration utility. Typically, these are dual graphics cards, using nVidia's SLI technology or ATI's CrossFire.

You can find the 80GB to 200GB capacities hardly. Most office PC users often don't need a hard drive larger than 80GB, but for those wishing to handle a large data warehouse, store digital photo, audio or video collections. video, large hard drives up to 750GB are needed. Most of the current drives using Serial ATA standard have a rotation of 7,200 rpm (7,200rpm), but now there are drives for players with speeds of 10,000rpm to improve performance.

The screen is a device that you keep in touch with for hours, the 17 or 19 inch LCD is able to respond well to many people. Besides, there are 22-inch widescreen models sold at insignificantly higher prices than the 19-inch models. With a wide screen, users can enjoy sharper digital images via the DVI connector instead of the only analog standard on universal computers. This monitor has two display modes, compatible with two types of graphics cards with DVI ports or universal ports.

Some computers have both modems available for Internet access via dial-up phone lines and ethernet ports for broadband connections. Gigabit ethernet ports for internal network connectivity over a router are higher than conventional 10/100 ethernet products.

For office activities, users only need to have the sound emitted from the built-in card on the motherboard. Most new computers are capable of playback high quality audio with Intel's High Definition Audio (High Definition Audio) standard, replacing the previous AC'97 technique. This audio standard can emit 7.1 channel 192-kilohertz audio, compatible with sophisticated, new speaker systems. This type of audio encoded ring effect is suitable for entertainment needs watching movies or listening to music at home.
