Purchasing computers for your business can be a daunting task. There are so many brands and so many different types of computers. Which one is the best for you? While there’s no magic formula for choosing business computers, there are a few things to get  a good fit.

1. Buy at the Right Time

Buy at the Right Time ?  The best months of the year to purchase desktops are July, August, and September. This is when chipmakers start releasing their new processors, which prompts retailers to mark down their existing inventory to make room for the new computers. Also, many dealers offer “back-to-school” sales on the old stock at this time of the year. It can be on every early or end of the year when the dealers will make some promotion until the stock is clear.

2. Do I need a laptop or a desktop?

It comes down to how you use your machine. If you take it with you to meetings and trips or use it for presentations, then a laptop is a great option if you don’t require much heavy lifting for video processing or rendering. If you use it mostly as a “home base,” a way to keep all your important documents together in one place, or if you crunch lots of bits and bytes, a desktop is probably a better choice. When you know your type of business, it is easier to choose whether a laptop or desktop will be your best choice.

3. What processor will keep my business running?

The processor is the brain of your computer. If it’s slow, your computer will be slow. The speed of the chip will tell you how much data it can process in a specified time. If you want a fast computer that boots up programs in a flash, completes tasks as soon as you start them, and doesn’t keep you waiting, then you will want the fastest processor available. The processor is also the most difficult piece to upgrade. While you can always add more RAM or get a larger hard drive later on, you can’t upgrade your processor. Processors, or central processing units (CPUs), are the costliest part of a system. Processing power is the most important feature when you are deciding which computer to buy. CPUs are all about the numbers: The more “cores” a CPU has (anywhere between 2 and 8), the more data it can crunch. The higher the processor’s clock speed (measured in gigahertz, or GHz), the faster it runs.

4. Buy the Right Amount of Memory.

Look for at least four gigabytes of RAM. People who work in graphic design and in Web development are better off with 8GB to 16GB. More memory allows you to do two things: Open up more programs and windows at once and perform multimedia processes (like editing photos) faster.

5. Consider Your Extended Warranty Options.

For electronics consumers, most experts recommend not purchasing extended warranties. But you may want to consider your options for your business’s computers. Most business computers come with standard warranties of one, three, or five years for a new computer. Typically, within this period the manufacturer will either ship you a replacement part or send over a repair tech in a timely fashion. If you want faster response, you can buy warranties from some manufacturers for a guaranteed two- or eight-hour response times. Other options include “keep-your-drive” plans, accidental damage protection, and data recovery services. Whether you need these add-ons or not depends on what you need to protect, and your aversion to computer problems. But if you buy a second hand computer how long the warranty will be? There are not many shop giving warranty more than 1/2 months for this second hand item.
