转发我朋友给我的一封信，我不懂，请教大家：
Do you know if a AGP slot can be used with PCI E card?I am using AGPx8 card at the moment and would like to get a better one. Nowaday, graphics cards are PCI E and I am not sure if they would fit my motherboard (ASUS P4P800). The card I am interested at the moment is GForce 6800GT for playing 3D games. Let me know what you think.
谢谢大家。
我的问题是，PCI Express是插在普通的PCI白色插槽吗？还是插在AGP插槽的？
还是插在特定的PCI插槽？ 如果是，那么是不是PCI Express 1X , 2X ,4X, 8X,16X插槽的长度不一样？是不是16X的长度可以兼容低速的?谢谢大家。
