The PC gaming world will never fade away due to new innovations in technology and virtual interaction. Many famous titles offered on consoles originated on the PC. These games run smooth, fast, and with utmost quality on computers that meet recommended hardware requirements.
Without meeting these specifications, games will lag, graphics will suffer, and the overall gaming experience will be disappointing. Gaming hardware also adds value to any computer. Any processor that is below the Intel Core 2 Duo 2Ghz or the AMD Athlon 64x2 2Ghz will not provide a solid gaming experience. In fact, the aforementioned processors are the minimum requirements for certain top-notch games. For the best gaming experience, PC games require a an Intel Core i5 3.1Ghz or the AMD Phenom II X6. These specifications are high, but certain games also have recommended settings. Any processor between the minimum and maximum requirements will suffice.
This little chip must be placed in every computer to ensure that games run smoothly. Minimum requirements for RAM are anywhere from 2GB to 3GB. Typically, games will recommend at 3GB of memory for components in the game to run at moderate settings.
Video Card or Graphics Card
This component is usually the most important aspect of a gaming desktop. This is because most modern games use high-end system requirements to run smooth. If you intend either to purchase or build your own gaming PC, then this is the first spec you should focus on. nVidia graphics cards offer solutions for multiple video card usage via SLI (Scalable Link Interface) technology, which allows you to hook up minimum 2 cards to run in parallel for extreme gaming performance and visuals. They also have support for multiple monitors and true 3D gaming. If you choose to go with graphics cards that support 3D gaming, you'll also get a pair of 3D glasses and you have to get a monitor that supports displaying 3D visuals. ATI video cards offer the same solutions, even for multiple graphics cards, but in their case it's called CrossFire. With CrossFire you are not limited by the model of the card, and you can use slightly different graphics cards to achieve better gaming performance. Prices for intercoolers vary but they are crucial for PC games. Intercoolers will prevent the hardware in your computer from overheating when playing for an extended period of time.
