Gaming desktop computers are built to process the huge amounts of information available while playing massive role-playing games or first-person shooters, especially while online. These games contain incredible detail and often require quick reactions. A gamer is only as good as the computer on these games, and the difference between success and failure could lie in whether a computer lags a second or two behind. Many of these computers use liquid cooling technology.

Gaming desktop computers are also built to conveniently handle all the peripheral devices that go along with those games, including ports for joysticks, steering wheels and any other devices. They are also built with more style and portability than normal computers.

Some of the cheapest gaming desktop computers are those that are built specifically by the person who will be playing them. Often a gaming PC just as powerful can be found for the same amount of money.

The other option is to purchase a specific gaming computer that has been built for that purpose. A cheap gaming desktop can be had for around $1,500, while others can run as much $8,000.

Regardless of which option is used, there are a few things the buyer should keep in mind. A fast central processing unit (CPU) will help prevent the lag that can occur during massive online role-playing games. Some of the best gaming PC units will contain dual or quad core processors for those indulging in extreme gaming experiences.

Memory is also important for successful PC gaming. A large amount of memory is necessary to allow the gaming computer to quickly access programs it uses on a regular basis. The best gaming desktop PC will have at least two gigabytes of RAM memory and could have up to eight gigabytes.

Many computer games have realistic-looking graphics, but without a high end graphics card the images will not look nearly as good as they were intended. Graphics cards often can be upgraded.

With a desktop gaming computer, the whole package is important. A fast central processing unit and lots of memory will not be enough if the graphics card is below par.

Investing in a good desktop gaming computer can mean the difference between life and death in the often realistic and complex world of online gaming.
