除了显卡驱动，还有哪些设备驱动可以优化系统的性能？

Resation

　　显卡可以使用通用的 vesa 驱动，但效果要比厂商（比如 nVidia）提供的官方驱动差很多。以此类推，我的网卡和声卡虽然能被识别，是否存在更好的驱动呢？除了那些板卡，还有哪些硬件可以装上更好的驱动呢？

　　硬件参数如下，大家帮忙看看。

话说回来，我的系统重装一次后，感觉声音变小了。

我用ati的显卡.那叫一个麻烦.

除了显卡，似乎没有其他的驱动比内核的更好了。当然声卡有商业的OSS驱动，不知道是不是更好。有的厂商支持开源，直接贡献代码给内核了，没有其他专门的驱动了吧。
一般来说，不开源的东东只能厂家提供驱动才有可能发挥最佳的效能，这是没办法的事啊。
