gforceThe big trend for the market of video games are the games with high level of detail, the Massive Multiplayer Online Role Playing Games – MMORPG, Online RPG games – and the First Person Shooter – FPS, in which the player assumes the position of shooter. Some examples of success are World of Warcraft (MMOPG), Battle Field and Call of Duty (both FPS).

O crescimento desse mercado tem impactado diretamente no aumento da procura por computers, placas e processadores que possibilitem a boa reprodução dos Games. Graphics cards, processors, placas-mãe agora não são assuntos restritos aos profissionais da technology, but are also topics of discussion among gamers.

But, What will be the key to making good use all the functionalities of 3D games or in high definition? Será que um monitor de qualidade é o suficiente? A monitor only reproduces faithfully the details of the images if the graphics card has high processing speed. Then, the tip is: to fully enjoy all the details of the games, Choose a high performance Board.  Translating: the graphics card processor transforms data into images, filling in the pixels of the screen. High resolution games, the computer chega a fazer esse processamento de pixels mais de 60 times per second.

And how to choose a graphics card?Currently, most graphics cards have at least 512 MB of memory, but, more important than storage is the ability to transfer data. Choose equipment with a good memory (DDR 3 ou 5, they are potent to accompany the processor speed),and a good band (128, 256 ou 384 bits). Toore responsible for the communication between the memory and the graphics processor, the band is vital for good reproduction of graphics of the games.

To calculate the data transfer capacity, We must multiply the frequency of (in mega-hertz, MHz) by the band (in bits) and divide by eight. Hard? Let the example. In a video card 512 MB, DDR 4, 2.250 MHz, 256 bitsMHzll have: 2.250 x 256/ 8, resulting in 72 GB/s. Optimal data transfer speed.

Having a good ability to transfer, make sure that the cooling system of your Board is efficient. Complex graphics processing requires a lot of equipment, heating it up and, without a good cooling system, the card overheats and your fun can last bit. Check the CPU fan and blower, When in use, make periodic reviews for cleaning, avoiding swishes and overheating.

Finally, but no less important, It is possible to find dedicated factory overclocked cards, IE, with the optimized performance through a process that leads to maximum power equipment, surpassing their limits and doubling the performance of the computer. If you choose a card without overclocking, can make the process at home through a software. But stay tuned: factory overclocked cards have higher income.

With a good graphics card, processor and monitor, just choose the game and enjoy the fun.
