如今，在电脑配件的选购中，最让人难以选择的恐怕就是显示卡了，在我们购买显示卡前应该对它多少有一些了解。显示卡也就是通常我们所说的图形加速卡，它的基本作用就是控制电脑的图形输出，可以说它是一个“中间人”，它工作在ＣＰＵ和显示器之间。通常，显示卡是安装在电脑主板的扩展槽中或集成在主板上（多为品牌机）使用。 Today, in the purchase of computer accessories, I am afraid that the most difficult choice is the graphics card, we should buy it before you have some understanding of it. Graphics card is what we usually refer to the graphics accelerator card, its basic role is to control the computer’s graphics output, it can be said that it is a “middleman”, it works in between the CPU and the monitor. Typically, the graphics card is installed in the computer motherboard expansion slot or integrated on the motherboard (mostly brand machine) to use.
