Things to consider when purchasing a desktop

Things to consider when purchasing a desktop

While many choices are likely to be dictated by the size of your budget, there are also a number of practical considerations to bear in mind.

  • The first choice you need to make is whether to opt for a PC or a Mac. Before you make a purchase, consider which system you prefer using (Mac OS X or Windows) and try to predict whether or not you might expect to encounter any compatibility issues along the way.
  • Another early choice to make is between all-in-one desktops and tower desktop computers. If desk space is at a premium, consider an all-in-one with touchscreen functionality. If you want a desktop that can be easily upgraded, opt for a tower.
  • Consider the kind of software you intend to use on your desktop and draw up your wish list accordingly. If you plan to use video editing programs, for example, look for a desktop with large memory.
  • Do you intend to use your desktop for gaming or as part of your home theatre set up? If so, you should consider purchasing a desktop with a dedicated graphics card.
  • If you own a DVD or Blu-ray library, consider purchasing a desktop with an optical disk drive. This will allow you to turn your computer into a first-rate media player.

All-in-one Desktops

All-in-one Desktop Computers

All-in-one desktops are ideal for families, homes where space is at a premium and for anyone who dreads the thought of configuring a computer. Setting up an all-in-one is easy: simply take it out of the box, plug it in and turn it on.

  • An all-in-one desktop contains the computer components in the area behind the monitor’s screen so all you need to find space for is the unit, the keyboard and the mouse. Surprisingly slimline, all-in-one desktops help you keep your desk and floor clear from clutter.
  • Many all-in-one PCs come with touchscreen functionality. As well as offering you a new and exciting way to interact with your computer, touchscreen capabilities also mean you can do away with your mouse to save even more desk space.
  • If there is a drawback with all-in-one computers, it is that they are harder to upgrade than tower desktops. If you are looking for a computer that you can customise or develop over time then an all-in-one is not for you.

If you require a computer for completing straightforward tasks like word processing or surfing the Internet then you can save yourself money by only paying for the features and functions that you need.

  • If your computer will be for emailing, browsing and using software like Microsoft Office, then you don’t need powerful processors or large RAM. A desktop with an Intel Core i3 processor and 4GB of RAM will likely suffice — and be affordable on a modest budget.
  • Most entry-level computers come with around 500GB of storage space. This will be more than adequate if you only need to save documents and a small number photos. Storage space can be easily upgraded by adding a new hard drive to the tower or purchasing a portable hard drive, which you can connect to your computer via USB.
  • If you only need a computer for occasional use then you may wish to opt for a PC with Windows 10. Depending on the spec, PCs tend to be more affordable than Macs and offer just as much functionality.

Aim for a computer that has a card with the largest number of cores, highest clock speed and biggest memory bandwidth that you can afford.
  • CPU speed and RAM is less important than a dedicated graphics card when shopping for a gaming or multimedia desktop. However, to ensure performance is not hampered by other components, don’t opt for a computer with anything less than an Intel i5 processor (or equivalent) and 8GB RAM.
  • If you plan on using your new desktop as a multimedia hub then you may also want to consider models that include a Blu-ray ROM/DVD burner combo and TV tuner cards that allow you to watch television on your computer.
