Video Card Differences

Hi,

What is the difference between an AGP and a PCI Express video card?

Thanks.

PCI Express uses several serial channels to communicate with the rest of the system, and AGP uses a parallel bus. PCI-Express can achive a very much higher bandwidth than AGP can, but it won't realluy come into its own until graphics cards become faster. With current cards there isn't a great deal to choose between them, performance wise. Here's a quite good article:

If you're planning an upgrade, it is worthwhile getting a PCI-E compatible motherboard, but as Nick mentioned, it won't really exceed itself until things advance even further.(Direct X10 PS. 4 etc)
