If you're not too well-versed in computer specs, scroll to the bottom of this page where we've put together a short FAQ. The products on the list have been picked by our experienced team of reviewers, who personally test and review all the latest computers and laptops. Their findings and opinions inform our comments in this guide - check out our page on how we test computers for more detail. As mentioned, we're covering desktop computers here, so if you don't buy an all-in-one computer like an iMac, you'll also need one of the best monitors to see what you're doing. If you would prefer a laptop then don't fret - we've also got a dedicated guide to the best laptops for graphic design. Plus, don't forget that you'll also need the best graphic design software. Graphic designers and iMacs go together like peanut butter and chocolate, so you probably won't be surprised to see an iMac at the top of this list.
The defining feature of modern computers which distinguishes them from all other machines is that they can be programmed. That is to say that a list of instructions (the program) can be given to the computer and it will store them and carry them out at some time in the future. In most cases, computer instructions are simple: Add one number to another, move some data from one location to another, send a message to some external device, and so on. These instructions are read from the computer's memory and are generally carried out (executed) in the order they were given. However, there are usually specialized instructions to tell the computer to jump ahead or backwards to some other place in the program and to carry on executing from there. These are called "jump" instructions (or branches). Furthermore, jump instructions may be made to happen conditionally so that different sequences of instructions may be used depending on the result of some previous calculation or some external event.

Closing the laptop protects the screen and keyboard during transportation. Laptops generally have a rechargeable battery, enhancing their portability. To save power, weight and space, laptop graphics chips are in many cases integrated into the CPU or chipset and use system RAM, resulting in reduced graphics performance when compared to desktop machines, that more typically have a graphics card installed. For this reason, desktop computers are usually preferred over laptops for gaming purposes. Unlike desktop computers, only minor internal upgrades (such as memory and hard disk drive) are feasible owing to the limited space and power available. Laptops have the same input and output ports as desktops, for connecting to external displays, mice, cameras, storage devices and keyboards. Laptops are also a little more expensive compared to desktops, as the miniaturized components for laptops themselves are expensive. A desktop replacement computer is a portable computer that provides the full capabilities of a desktop computer.
7. Exercise your eyes. Another cause of computer eye strain is focusing fatigue. To reduce your risk of tiring your eyes by constantly focusing on your screen, look away from your computer at least every 20 minutes and gaze at a distant object (at least 20 feet away) for at least 20 seconds. Some eye doctors call this the "20-20-20 rule." Looking far away relaxes the focusing muscle inside the eye to reduce fatigue. Another exercise is to look far away at an object for 10-15 seconds, then gaze at something up close for 10-15 seconds. Then look back at the distant object. Do this 10 times. This exercise reduces the risk of your eyes' focusing ability to "lock up" (a condition called accommodative spasm) after prolonged computer work. Both of these exercises will reduce your risk of computer eye strain. Also, remember to blink frequently during the exercises to reduce your risk of computer-related dry eye.
