A couple of the aspects that set the price of your pc are size (yes it does make a difference) and speed. One or both of the two dimensions are a factor of practically every element that comprises the device. Obviously the largest price tags go with the mix of biggest and fastest.

CPU
The heart of the personal computer is the cpu (central processing unit). You have to choose which Processor you want driving your computer. These come from different manufacturers, and the present development of the technology is called Multi Core, meaning that there are multiple processors on the one chip. Multi Core technology gives far more performance with less power needs. Intel and AMD are the two top CPU producers, and you can purchase various products under various names.
Current processing rates range all the way from about 1.4 GHz (gigahertz) right through to 4.5 GHz. Yet it's not merely just a matter of speed. There are some other things to consider. Mac Operating Systems have a distinct architecture to Windows and will carry out many functions more rapidly with a reduced speed Processor. A dual core processor chip at 1.4 GHz will generate a significantly better overall performance than a Pentium 4 chip at 1.8 GHz. A 1.4 GHz dual core chip operating a Mac with OSX Tiger, will perform better than a 2.0 GHz Pentium 4 chip driving Windows. You'll want to decide what you wish your computer to do, what your key software necessities are before you make a decision on the CPU processor.
Harddisk
The harddisk of the pc stores your software files and your information. As computer systems have developed so has the importance for higher capacity to operate programs and keep files Individuals working in media areas normally to work with very large files and need large storage space. The majority of computers in today s marketplace contain a minimum of 500Gb of local disk space. Even so this can be improved typically in 500G chunks to as much as 2Tb (Terabytes) or more The overall performance of your hard disk can also vary depending on its physical speed 5400 7200 RPM and the rate in which it can transmit data in between the pc s Ram memory and the hard disc drive. Faster implies significantly better performance
Removeable Media
You'll need to have a CD-R or (CD-RW) drive installed in your pc,or in all probability a DVD or DVD-R. For reading a CD ROM, all that is required is a CD drive and for playing DVD films, a DVD ROM drive. However with a CD-R drive, it is possible to record your own data and music CDs, and with a DVD-R drive, you can burn files in a DVD format, which allows you to store videos and files in far larger sizes. The CD-RW (DVD-RW) drives permit you to gain the benefits of re-recordable media. Your decision will depend on what you would like to use your media drives for and what you need to preserve. Other removable media will comprise flash card storage, that is generally connected in via the USB ports on the pc.
Graphics And Audio
The interface between the Computer and the Display is given by the video card. One of the necessary choices you must carry out is whether or not you must have a 3D or 2D card. Video cards come in two different varieties: ones that use an AGP (accelerated graphics port) on the pc motherboard and others that use the PCIe bus. Data transmit rate is critical to graphics performance. Speedy video cards use PCIe, and this proves a faster data transmission than AGP cards. As a rule video cards also have their own video memory placed on the card, a characteristic that boosts a computer's memory functionality. Right now, these memories are often 1Gb or 2Gb, and are usually more in the higher-end cards devoted to professional graphics work or video gaming. Video cards overall performance is also influenced by what is known as clock speed or clock rate, cards with a faster speed offer better performance.
