Gaming computers are specialized personal computers designed for playing video games. Gaming computers typically differ from mainstream computers by using high-performance video cards and high core-count central processing units that sacrifice power efficiency for raw performance. Gaming PCs are also used for other demanding tasks such as video editing.
Many gamers and computer enthusiasts choose to overclock their CPU(s) and GPU(s) in order to gain extra performance. The added power draw needed to overclock either processing unit often requires additional cooling, using upgraded air cooling or water cooling.
