Ever since the computer gaming boom, several types of computers have hit the market. Now there are systems made specifically for work applications or casual use, as well as powerful notebooks and desktop computers that are made to play even the most demanding games. These so-called gaming computers generally have a lot of RAM memory, multiple core processors and exceptional graphics cards. Basically, in gaming computers a lot of attention is paid to the components that are required to run even the most advanced games without having to worry about common performance problems, such as lagging, crashing or overheating. The hard drive space available is also important if a computer is to be used for gaming, because most games now encompass several gigabytes and that number only goes up when mods, or add-ons, are added to the core content.
