If you are thinking about a desktop, look for a system that is comparable to (or better than) the Dell Optiplex 9020 example system (see PDF below). You will want at least 4GB of RAM (8GB preferred), an add-in video card, and a good sized monitor. The monitor's size depends on what you like or have room for on your desk, but most people seem happy with something in the 20" to 22" range. Whatever the size, you want the text and images to be sharp and clear. Remember, you may spend quite a bit of time staring at it so you want it to be easy to read. A three-year on-site warranty is alsoincluded in the example system.
