Business PC

To buy or not to buy?

Coming up to Christmas is a good time to consider whether you need to upgrade or replace your PC. “My PC is old and slow, should I buy a new one?” is a common question and there is no simple answer.

Why do I need a PC?

When asked the question, “what should I buy?”, I always ask “what would you like it to do?” The response can result is some head scratching, but should include some of the following:
  • Run farm management software
  • Use Office application software, for example, spreadsheets, writing letters, simple databases,..
  • Connect to a small business network (wireless(Wi-Fi) or wired)
  • Store important business documents and information
  • Browse the Internet
  • Communicate using Email, Fax or VOIP (Internet telephone)
  • Store and play music
  • Store and view photos
  • Even play games!

PC Specification - Common Components

How much RAM do I need? Which processor is best for me? Do I really need a Wi-Fi adaptor? When you are specifying your new PC more performance/features will cost more. Consult with your farm software supplier to specify a PC that meets the requirements for their software. Use these as a guide when specifying your new PC. You should be purchasing a PC that will meet those needs and not buy something that is over or under specified:
  1. Processor - Intel Core2Duo or AMD Athlon64X2 This is the easy one, at today's prices, specify an Intel Core2Duo processor (or AMD equivalent). These processors range from the very quick T2000 series up to the enormously fast T6000 series. Even the slowest Core2Duo processor will meet all the business needs of any farming enterprise.
  2. Memory - 1GB (XP) or 2GB (Vista) Most new PC's will come with at least 1GB of RAM. While this is adequate for all farm business applications if you are using the new Windows Vista operating system, you will see benefits from upgrading to 2GB RAM
  3. Hard Drive - At least 60GB. Information such as accounting or herd management data does not require a large amount of storage space. Only multimedia files such as videos, music and photos will require more storage space. If any of your information is business critical, have a data backup procedure in place. Do NOT rely on a single storage location, especially if you are using a laptop. Removable/external storage such as recordable DVD or USB Hard drive are both cheap and effective backup solutions, please use them.
  4. Graphics Card - A dedicated graphics card is designed to improve the look of modern computer games and some high definition video playback. So unless you fancy a few hours on the latest flight simulator between milking’s, expensive graphic cards are best avoided.
Network Access - Your new PC will have a wired connection for a home network built in and most laptops will also be fitted with a wireless card. If you purchase a desktop, you may have to purchase an additional Wi-Fi card to allow access to a Wi-Fi network.

Where should I buy my new PC

Compare the price of your required PC from various sources, compare like for like, and only buy what you need. Many retailers will have desktop PCs (including monitor) with the above specification for under £400 (ex VAT). If you want to see before you buy your choice will be between a local independent supplier or one of the larger computer supply outlets. Personal service, advice, warranty support, delivery and installation options are all areas to be considered when making the choice.
If you know what you want the cheapest source is often from one of the many reputable online retailers. There are things to be aware when ordering online, such as, stock levels, delivery charges and returns policy.

Next month I will discuss more about online shopping and e-commerce and how your farm business can benefit from using the internet
