Buying Guide
Buying a new computer can be a tough decision with so many different and important elements to consider. With technology advancing so quickly it is important to try and think what your future computing needs will be as well as your present requirements. If it’s a desktop PC for the home or a mobile laptop to use on the go we have what you are looking for with prices to suit all budgets.
What will you need to get your PC up and running? And what will you need to access the wide range of facilities available through your PC? From printing high quality photographs to connecting your PC to your home network for sharing HD content and watching downloads, we have all you need to get the best from your PC.
Things to consider when buying a new PC:
Processor
The processor is the PC’s brain, the processor drives performance and quality of applications. The processor speed is shown in Gigahertz (GHz), the higher the GHz the faster the processor. Our computing range features both Intel and AMD processors from standard everyday use to ultra fast advanced processors for home entertainment and gaming.
RAM (Random Access Memory)
RAM is the PC’s working space where work progress is stored and is measured in Kb and Gb. The more RAM your computer has, the more efficiently it will perform. 1GB of RAM is suitable for running everyday tasks such as emailing, browsing the internet and word processing, for running numerous applications together 2GB of RAM upwards would be required. For gaming and home entertainment requirements 3GB – 4GB of RAM is optimum.
Hard Drive (HDD)
The hard drive is where images, software, music files and all data is stored. HDD is measured in Gigabytes (Gb) and can go up to Terabytes (Tb), the higher the figure, the more storage space. External hard drives can also be used in conjunction with the main hard drive, these can be used to increase the computers hard drive capacity and/or to back up important files. The table below shows the volume of files that can be stored on your computers hard drive. *
| Capacity | Digital Photos | Songs (MP3) | DVD quality video (hours) | HD Video(hours) |
|---|---|---|---|---|
| 160Gb | Up to 45,000 | Up to 40,000 | Up to 71 | Up to 19 |
| 320Gb | Up to 91,000 | Up to 80,000 | Up to 140 | Up to 38 |
| 500Gb | Up to 142,000 | Up to 125,000 | Up to 220 | Up to 60 |
| 750Gb | Up to 214,000 | Up to 187,000 | Up to 330 | Up to 90 |
| 1Tb | Up to 280,000 | Up to 250,000 | Up to 440 | Up to 120 |
* Available capacity dependent on operating environment and file size
Optical Drive
Optical drives allow you to read and in some cases write discs in order to use CD’s, DVD’s, load and install software and write data to discs.
- CD-ROM - only reads CDs
- CD-RW - Record and play CDs
- DVD-ROM - reads CDs and DVDs
- DVD RW - Record and play CDs and DVDs
- DVD Dual Layer - Loads double DVD
If you are looking for high definition (HD) playback then look for items that have a BluRay drive. BluRay drives also plays CD’s and DVD’s.
Connectivity
To get the best from your PC you may want to consider how to connect to other devices to utilise some of the more advanced applications
Bluetooth wireless technology is a short-range communications system intended to replace the cables connecting portable and/or fixed electronic devices. Bluetooth uses radio waves to wirelessly link compatible laptops, mobiles, scanners etc within 100m radius (dependant on conditions) and allows users to view contents of a mobile phone on a PC.
Wi-fi is wireless networking - the ability to connect to a network or PC using radio signals (as opposed to network cabling). It's faster and has a greater range than Bluetooth, and is ideal for home or office connectivity. Check www.jwire.com for wireless hotspots.
Graphics
- Integrated graphics – a graphics processor/chipset is included on the computers motherboard. The integrated chipset requires memory so will be shared from the main PC RAM.
- Dedicated graphics – this is a separate card fitted into a computer that has a graphics processor and its own dedicated memory, ranging from 64Mb up to 512Mb.
If you require your PC primarily for surfing the net or doing general computing like word processing and creating spreadsheets integrated graphics will be sufficient to do this. If you want your PC for multimedia projects or gaming then look for dedicated graphics with the higher the dedicated memory the better.
