Can someone explain to me what it is, how its different from AGP, and what advantages it offers compared to AGP?

Thanks!

Definitions of PCI Express on the Web: (G00GLE

)

* an emerging (2004/2005) standard for high-speed graphics, likely to result in a 20% boost over 2003-era AGP 8x performance. The standard, supported by ATI and other vendors, delivers better power management, bi-directional simultaneous I/O and 4GB/s bandwidth.

* PCI Express (formerly known as 3GIO for 3rd Generation I/O, not to be mistaken with PCI-X) is an implementation of the PCI computer bus that uses existing PCI programming concepts and communications standards, but bases it on a much faster serial communications system. It is being supported primarily by Intel, who started working on the standard as the Arapahoe project after pulling out of the InfiniBand system.

In short,PCI express is faster than AGP and it is backwards compatible with other devices.

Will it work on a regular PCI slot or will there be a specific slot designed for it?

You need a motherboard that supports PCI-X in order to fully use PCI-X. There is currently no reason why you'd put a PCI-X graphics card in non-PCI-X slot.
