New installed five big misunderstanding

CPU performance is the most important, other hardware doesn't matter

At present, many users believe that the performance of the CPU is equivalent to the performance of the machine, this view is wrong. CPU performance in the whole machine plays an important role, but want to play all the performance needs of other hardware to use it.

Give a classic example, called the cask effect. A computer compared to a bucket, each of the hardware on the computer compared to wooden barrels of wood, a single hardware product performance is the higher the corresponding chips, hardware product performance is weaker then the corresponding chips shorter.

When assembled, inject water into the barrel, at this point the more water to prove the performance of the machine, but this time the bucket can carry water does not depend on the longest piece of wood, but depends on the shortest piece of wood, when the water over the shortest wood, the bucket of water will be left out, at this time is the highest performance of the machine.

So we are in the purchase of computer accessories, the overall performance balance is the most important, do not only pay attention to one of the hardware performance, so not only performance can not be upgraded, but also a waste of money.

Conclusion: The purchase of CPU or according to individual requirements, and then other hardware according to the CPU performance reasonable collocation is the best way to maximize the performance of the machine.

Motherboard as long as the number of brands, the other is garbage

Motherboard is a computer's torso, almost all the accessories are connected with the motherboard, so choose a good motherboard can effectively play the computer components of the performance. Many netizens because of the advertisement or various reasons influence, blindly pursues the first-line big factory's motherboard, this is not the bad thing, because the first-line large manufacturers research and development ability, the quality is excellent, the performance is outstanding. But our ordinary consumers often rarely pay attention to more than the products, more or more cost-effective focus on the 600-700-yuan motherboard, but the price of the first-line motherboard work is often unsatisfactory.

Compared with the first-line motherboard, the second-tier motherboard price will be lower, and the workmanship will be better than the low-end products of the first-line manufacturers. For the performance of a motherboard, the importance of working materials is entirely higher than the brand effect.

Conclusion: The pursuit of cost-effective friends choose the second-line motherboard, the price will not be too expensive, the work of the materials are also more assured. For enthusiasts and high-end users of the top-line manufacturers of high-end motherboards is your choice, a wide variety of tricks, will make your DIY career more fun.

Video card memory more dozen better, display core is not important

The user's knowledge of the graphics card is often shallow, according to the view of the memory of the video card is the current user's universal existence of a shopping error. Current graphics card mainstream memory for 128MB, high-end card will use 256MB video memory, but some of the market card is obviously using entry-level chip, but it is equipped with 256MB or 512MB of large memory, compared with the display of the core show Kagui 200 yuan, but many users flocked.

At present, the mainstream graphics card memory is basically 128MB, but with the large capacity of the RAM grain prices drop, many graphics card memory capacity is upgraded to 256MB or higher. So many users at the same time the memory capacity of 128MB and 256MB with the display of the core of the graphics card will often be considered to be 256MB video graphics card performance is stronger. From some evaluation reports, 256MB video memory can only bring 2%--7% performance improvement for high-end cards, but less for medium and low end graphics cards.

In addition, currently equipped with 256MB video memory of the medium and low-end graphics card memory particle delay is relatively high, so the actual performance is often inferior to the 128MB video memory of the high speed memory particle graphics card. And the benefits of large video memory only in large 3D games using large resolution or in the field of graphic design to show the advantages, therefore, I suggest that you do not blindly pursuit of large memory.

Conclusion: The video memory is good enough, the low-end 128MB is sufficient, the high-end 256MB is just, the top card is no more idle.

Dual card and Tanka selection error

In recent years, there has been a great change in graphics design. Nvidia introduced the SLI dual-card technology, ATI introduced the Crossfire dual-card technology, two technologies using their patented technology, incompatible between each other through two graphics cards to help each other to improve the overall 3D performance.

But through our testing of the dual-SIM platform, dual SIM platform is not able to bring us a huge performance improvement, SLI performance is often more than a single card to promote 25-30% around, Corssfire will be a little less, and we need to pay is two graphics card money, this for the pursuit of cost-effective you are unable to identify.

But whether the dual card technology is useless, the answer is no. Dual-card platform from the beginning of the design for high-end graphics card design, in view of the current performance of single cards to improve the plight of the weak, through the dual-SIM work to improve the overall performance. For enthusiasts who need extreme performance, top cards are no longer enough to meet their needs, and the two top cards are his choice.

Conclusion: According to the choice of their own needs, low-end users do not recommend the choice of dual-card platform, recommended high-end users using dual-SIM platform to provide speed performance.

Keyboard mouse, chassis power supply and other hardware can be used on the line

Keyboard mouse, chassis power supply in a whole machine price is often small, although Occupy 4 seats, but often by people neglected.

Mouse keyboard as a computer communication bridge, they directly affect the overall efficiency of our work. A good keyboard and mouse will make your overall productivity more efficient, this is reflected in the Office, games and many other fields, the Office field keyboard Mouse is often embodied in their multi-function keys, more functional key design, and ergonomic design can partially relieve the hand muscles, not only improve work efficiency but also conducive to health.

Chassis power is the most easily overlooked two hardware, one is to put our hardware boxes, one is the power of the box, it sounds unimportant, but their position in the machine is irreplaceable.

The quality and design of the chassis are essential to our future use, good quality chassis often sound insulation, heat dissipation, deformation and other aspects more dominant, sound insulation so that we have a better working environment, cooling can make our machine work more stable, prevent deformation can maximize the security of our computer hardware, indispensable.

Power is our lifeblood of a machine, it provides us with the power to survive, but many users will often think that as long as the power of other indifferent, this is not true. Although the power supply is very important, but other aspects also occupy a very important position. With the hardware for the power requirements of the more and more high, power, stability, etc. for the power supply is a test.

Conclusion: Chassis power selection of brand-name manufacturers, do not understand when you can listen to other friends advice, Word-of-mouth good product is your best choice.
