Market is flooded with lots of desktop computers of different configurations, shape and sizes. The main points to look for when buying a computer are the best combination of features, quality, performance, support, and price. Let us consider some points which are important when buying a computer.
Choosing a Computer Processor
The CPU is the main core of a computer system. It is mounted in a socket on the motherboard and it controls the entire computer’s other components. The performance of a computer is mainly depends on the type of CPU used and this puts some impact on the cost.
Intel and AMD are the two major manufacturer of CPU. These two manufacturers provide several families of CPU having different sets of features and designs. So if you are looking for speed and performance the price of CPU will certainly increases. It becomes necessary that you first decide what kind of computer work you would like to perform in order to choose a computer CPU. If you are dealing with some work which require high amount of CPU power then you have to look for high performance CPU. But on other hand if you are buying a computer to carry out simply daily tasks then you should go for normal CPU.
The main reason to buy a better and high performing CPU is to make it compatible for future upgrades or updates in latest hardware and software. You should opt for mid range CPU which will run for long period and get adapt to upgrades easily.
Speed of Processor
Speed really matters when you have to process a large amount of data or you are running some heavy application on your computer system. But on other hand if your work is restricted to only doing some routing home or office task like word processing or web browsing then you don’t have to go for such high speed of processor. But always remember don’t go for a cheap processor because it will become obsolete for the future programs.
So the best method is to go for middle range PC having good speed with low cost. As said previously you need to know your requirements first and after that choose wisely which type of processor you really need.
Choosing Computer Memory
Every file or program when runs in a computer it first get loads into RAM (random access memory). RAM chips are mounted as memory modules in sockets on the Motherboard. Data is exchanged between CPU and memory every time you save or open any programs on your computer.
Every Manufacturer has laid down some specification on the amount of RAM needed for a particular system but the actual demands of your computer system mainly depends on the amount of data process by CPU and the amount of programs you run on your system.
Windows XP needs minimum 256 MB of RAM but if you want to use some advanced programs like video editing, photo editing where a huge amount of data is processed you should increase your RAM up to 1GB for faster performance.
Choosing a Hard Drive
Hard Drive stores all your data and program files. Choosing a hard drive depends mainly on the amount of data you want to store. If you want to store large amount of songs, graphics, want to play games and videos than you should go for 300GB of Hard Drive.
When choosing a hard drive please remember the following points
Hard Drive Speed: Hard drives generally come with speed of 7200RPM and 5400RPM. It is always a good idea to choose a hard disk of high RPM because it will be easy to locate large amount of files on your computer. Your operating system will load fast when using a high speed hard drive.
Interface: Interface is a system by which computer exchange data with disk drive. There are commonly two types of interface used by computer system called ATA and SATA. SATA is the latest technology as compared to the older. SATA is relatively faster than the ATA and process large amount of data between hard drive and computer.
Buffer: A buffer holds the temporary data that the computer recently read and is going to be used again. Buffer increases the amount of time taken by processor to process the data. Desktop computer have either a 2MB buffer or an 8MB buffer. If you want to play heavy games on your system than go for at least 8MB buffer.
Choosing a Motherboard
Keep in mind that before choosing a Motherboard you should choose a processor. Motherboard generally supports only one type of processor such as Intel Pentium 4 or Athlon. So keep in mind that you should buy a motherboard that can support the type of processor you have with you.
Always make sure that you choose a compatible RAM for your motherboard. DDR 2 RAM are generally very popular these days because of the speed and low cost.
Following are other things you should keep in mind while choosing a motherboard
- Chipset support
- SATA Support
- Processor Support
- Expansion Slots
- On Board Features
