Computer gaming is one of the most popular form of entertainment today, and the computer industry is continuously trying to catch up with increasingly more complex and demanding games. Most 3D games require heavy processing power and powerful graphics processing units (GPUs), the latter of which should be considered a top priority before deciding for a laptop suitable for gaming. Here are a few points to consider when looking for a gaming notebook that will meet your needs.

Processor speed: Although it is secondary to the GPU, the processor should preferably be a fast onea 1.6GHz quad-core processor or better from Intel will deliver more processing power for your games but also much improved overall system performance.
Any gaming laptop must have a dedicated video card, meaning that it is a separate piece of silicon with its own internal memory (RAM). 1GB of GDDR3 is a bare minimum, but a larger amount of GDDR5 will help.
Hard drive speed has no effect on your games’ frame rate, but it certainly affects loading times. Try to aim for a drive that rotates at 7200 rpm, or even better, a solid state drive (SSD.
Laptop screen size: This is a matter of personal preference, but a 17-inch or larger high-resolution panel gives you a more fulfilling gaming experience.
Battery life: This is unfortunately never a strong suit for large and powerful gaming machines, but newer notebooks with switchable graphics can provide extra hours of use away from the mains.
