Anandtech has posted an informative write up on PCI Express, although we have been hearing about it for last year or so, it has finally been set to become a reality next year once major graphics card manufacturers give it a push and OS/Chipset support is available... just like ISA however, don't expect PCI to disappear instantly nor your peripherals to become obsolete right away.

3rd Generation IO, or 3GIO, has been recently renamed PCI Express, and looks to be the replacement for the ubiquitous PCI bus, the most successful peripheral interconnect bus used in PCs. With support coming in the Intel Grantsdale chipset, along with Microsoft's next version of Windows, codenamed Longhorn, let's take a look at the technology that is designed to last the computer industry for the next ten years.
