Information extraction system of the computer, and the performance evaluation is given, can be implemented by software testing!
I, on the hardware health problems, avoid buying second-hand parts. Hard disk using the state's most valuable, as can be seen, this is a secondary hard drive. Memory, motherboards, graphics cards, optical drives, it can not determine whether it is second-hand. However, we can determine the presence of life of the hardware. It can serve as an important reference whether matching machine!
Second, the performance test for computer hardware can be found processor performance, graphics performance, memory performance, disk performance is the main focus of attention. However, this figure can not give a straightforward test results. Only on a different computer tests comparing the performance.
1, the first computer performance test
2, the second computer performance test
Therefore, we have to choose different tools to complete the test, generally differ significantly! But different emphases! Yet, this test, more targeted, give us a more intuitive application selection.
Application support for the game! Optional game a lot, the principle is very simple, the game configuration requirements for manufacturers to provide hardware, software testing were graded according to game makers of gaming, basic configuration, smooth configuration. Under normal circumstances we naturally aim is fluent configuration.
1, a key hardware graphics card, test content: video memory, and graphics chip. Graphics chip is likely to have the real potential of the video card, memory chip then determines the performance of the play, so the matching card when the first chip set, memory re-election, is very important. First card game to eat, so the graphics card is the most important performance indicators. We also care about the version of the graphics card driver problem, which can ensure the normal use of the card.
2. The second important hardware CPU, test content: the number of cores, frequency! Graphics card needs to support CPU, so hope everyone's attention! At the same time, pay attention to the Core frequency capability of the CPU. Cache is restricting factor.
3, the third is the hardware memory, we need to focus on the size and capacity of the memory frequency, memory type, memory configuration is actually based on CPU, motherboard supports an optional, if you want to upgrade hardware, I suggest, the highest price after, is to upgrade memory capacity, content capacity reaches a certain course, and then increase does not make sense. CPU and graphics card to play, need memory support.
4, the fourth hardware is hard, under normal circumstances, I choose SSDs and mechanical hard disk double-disc mode, solid state drive for system disk to enhance the application experience, mechanical hard disk as a data storage disk. If the home computer is relatively old, plus a solid state hard drive, it is a good choice to upgrade the system.
5、整体系统性能测试！我们会发现，最重要的硬件是CPU、显卡、内存。大家不要因此忽视了硬盘的重要性，这只是说明游戏的需求，在其他日常应用中，硬盘很重要。
三、 WINDOWS体验指数，计算机整体性能取决于最弱的那个环节！
软媒魔方测试，测量处理器、内存（RAM）、图形、游戏图形和主硬盘五大子项目的成绩，最终的基本分数则由最低子分数决定。
特别说明，很多朋友会被弄糊涂了，这是操作系统的对性能测试的设定！
1、桌面图形性能体现GPU的能力。
2、游戏图形：3d商务和游戏图形性能体现显存的能力。
如果测试指数太低，最好的办法是更换高级显卡，或者更新驱动程序。
我们选配电脑就是为了应用，生活需求是多方面的，硬件配置是用钱买来的，受到我们预算的制约，应用的流畅度，却和我们的使用习惯，有很大的关系！
计算机驱动管理是不可或缺的！当计算机出现卡顿问题的时候，我们第一个考虑的就是驱动的问题，可以使用工具软件对驱动进行管理。
娱乐是生活不可或缺的一部分，游戏应用能否满足，是衡量我们对计算机管理能力的一个量化指标。全面优化，让游戏环境更加流畅，很简单，一个点击就可以满足了。
