The Components of your Laptop or desktop
Two of the aspects that decide the retail price of your pc are size (yes it does really matter) and speed.

Processor
The guts of the computer is the processor (central processing unit). You'll want to determine which Processor you need driving your computer. These come from various companies in the industry, and the present development of the technologies is called Multi Core, meaning that there are multiple processors on the one chip. Multi Core technology gives a lot more performance with less power needs. Intel and AMD are the two leading CPU manufacturers, and they have diverse products under different names.
For ordinary use a processor better than 2 GHz will deliver excellent overall performance. As a rough rule of thumb select an i3 for low cost computing, an i5 for mid range costs or an i7 for greater.
RAM
This is definitely where bigger definitely means better performance. Random access memory is the system memory that enables the laptop or desktop to make full use of its programs and swap information between the hard disc drive and the program functions. It's highly recommended to match up the speed of the Ram memory of your laptop or desktop with the speed of the Processor. The more Memory you've got available for your applications to function, the more rapidly will your personal computer operate.

For graphics intensive work LCD monitors do not have the same ability to provide colours in gradients as CRT screens. Once more size matters. Bigger monitors cost more than smaller ones
Graphics And Sound
More affordable computer systems and portable computers and notebooks have an integrated graphics chip included in the motherboard instead of a discrete graphics card. This sort of configuration is not as effective or as fully functional as having a discrete video card which will enable far more comprehensive video gaming, the use of multiple monitors and much quicker and far better rendering of pictures As a rule video cards even have their own video memory mounted on the card, a feature that boosts a computer's memory overall performance. Nowadays, these memories are often 1Gb or 2Gb, and can be more in the higher-end cards dedicated to advanced movie work or gaming. Video cards efficiency is also impacted by what is known as clock speed or clock rate, cards with a faster speed offer better performance.
For your machine to recreate the sounds recorded in video games, videos and songs, it needs a sound card. In case you are a musician and performer and would like to record sound then you will need to be confident that you have excellent connectivity good midi access and at least 16 bit CD quality audio processing Sound cards give you the capabilities of full cinema surround sound, and the many subtle effects utilized by high-end video games.
Nearly any laptop or desktop includes a set of stereo speakers. Nonetheless it will pay to have a good listen to what you're purchasing. Make sure you listen to a program that you are acquainted with (take your own CD along) and analyze the sound in a quiet environment. Several speaker systems for computer systems have very poor frequency response and are underpowered. For desktop computer use that does not consist of a top quality listening environment this may be passable. But if you need to listen to tunes and watch films for the full effect, then you need to give some thought to purchasing a good quality set of speakers.
