Buy a New Computer

1. Decide what you need your new computer for. If you need one for work, a simple bare bones system with Microsoft Word (or OpenOffice.org) will suffice, but if you're an avid gamer then you'll want something more advanced. If you want one for gaming, skip to step 5.
2. If you need a work computer: consult companies like Dell or eBuyer, as they provide low-cost workstation deals for the "common user." On such sites, you can get a computer without a monitor for under $200, and a CRT (cathode ray tube) monitor costs under $50 (the fat ones that stick out at the back).
3. Work specs: for an average computer, get anything with over 1.5 gigahertz (Ghz) of processor speed. You should also get at least 512 Megabytes of RAM. Hard drives have dramatically increased in capacity and come with quite a bit: 40 gigabytes (GB) is more than enough for work (If you are installing multiple operating systems such as dual booting Windows and Linux you might want a larger hard drive such as 120 GB). Then you want a CD drive of any kind, and you also want a couple of Universal Serial Bus (USB) ports as many devices for the techno phobe are used through this.
4. Windows Vista takes a large toll on system resources, make sure you have plenty of memory to spare (1 Gigabyte of RAM is required for Home Premium) And try to get a dual or quad core processor, it will make your computer run faster. Linux and Windows XP are much less demanding on your processor and RAM, so if you want to save money it might be better to try to go for a XP or Linux computer to get the same level of speed of a more expensive Vista computer. (XP is not available anymore, but you can install it by yourself. You most likely have to install Linux by yourself.)
5. Get any kind of monitor you want. Get one that's at least 15" or you can't see; they range from 17-22" approximately for a CRT. A 17" can cost as little as £40 but for a 22" it costs £250. LCD monitors are getting cheaper and larger. There are also Widescreen choices that are a little more expensive, but becoming more favored.
6. Realize that you will need a good budget for a gaming machine. Visit Alienware (for more budget options) or VoodooPC (for more expensive machines). In high end gaming machines, you want a Core 2 Duo based processor, at least 1GB of high speed RAM (random access memory) and a high end graphics card.
7. If you are buying a computer to run an open source operating system such as Linux, it may be better to prefer distributors that allow to configure components (like Dell). This way you may clearly select devices that do have the drivers for your operating system (it is easy to check with web search). Many current distributions will have the latest kernel of Linux, which has a wide range of hardware support already built-into the operating system. Unusual, niche, or specialized hardware may need special configuration, drivers, or may not be currently supported.

TIPS:

• Sometimes an extended warranty is nice, however most of the time its not needed, for a computer at your workplace you should ask your boss before you buy a warranty.
• Most of the software you need can be found in Free/Open source variants online to download, so don't think you need to buy all the software you think you need unless you've checked it out online.
