A desktop computer is an important asset in the office or in your home. You need to be careful when shopping for a computer. A computer has many features and you should know how to distinguish these features. When you are shopping, you will be faced with many questions related to hardware. Hardware is evolving at a faster rate, and it is not surprising to get updates every month.
The first item that you should think about when you buy a computer is the CPU unit. Every computer owner knows that a higher performing processor is good for business. Think about Intel, AMD and other brand names. You have a wide selection to choose from. A good processor is very fast and it often contains many cores. The price may be a factor to those who are budget minded. Nevertheless, if you want a processor with better functions, you must pay. Check the reviews and ratings before you buy.
The second item to think about when buying a computer, is the memory.RAM memory is used in many computers.DDR3 RAM memory is found in advanced systems while DDR2 is used in cheaper models. A system with 4GB or more of memory is good. If you want your system to operate smoothly, then you must buy a system with more space. The speed of the memory affects performance, so make sure that the memory is fast. You can increase the amount of DIMM to meet your needs.
The hard drive is another important part of a computer. When it comes to the hard drive, it is all about size and speed. The bigger the size of the hard drive, the better. A high-speed hard drive with a large capacity is excellent. Increased capacity and higher speed all add up to improved system performance. As a rule, buy a system with a minimum storage capacity of 500GB.The average speed of most hard drives is 7200rpm.You can find better performing hard drives with a top speed of 10,000rpm.Look for the ATA interface. It is the best for installation.
The third thing to consider is the Optical Drive. Most optical drives are CD/DVD/BluRay. The latest computers come with a DVD burner.DVD burners are a basic feature in almost every computer whether cheap or expensive. The best system is one with a multi-format DVD burner. A multi-format DVD burner supports the -R/RW and the +R/RW formats.
A system that burns DVDs at 16x or more is preferred. Check support for dual layer media, LightScribe and BluRay.
The last thing to consider is a video card. There are desktop models that come with video card technology. You can choose from many types of cards. Consider the memory size, performance, output connectors and whether support for Direct X is provided. You will need special cards for gaming. A DirectX10 card with more than 512MB of memory is ideal.
