este enlace es justo al que me referia cuando decia que estuve
curioseando por la wiki. PEro cuando la base es cero... no se entiende
mucho :-(

> PCI Express (Official abbreviation PCIe, PCI-E often used, not to be
> mistaken for PCI-X) is a computer system bus that allows expansion cards
> with various capabilities to be added to a system. It is a flexible system
> intended to replace PCI, PCI-X and AGP. While PCI Express has the same
> software interface as PCI and can be bridged to PCI, the cards are
> physically and electrically incompatible. While in development, PCI
> Express was referred to as Arapaho or 3GIO for 3rd Generation I/O.

> lane has nearly twice the data rate of normal PCI, a four lane slot has a
> comparable data rate to the fastest version of PCI-X 1.0, and an eight
> lane slot has a data rate comparable to the fastest version of AGP.

> flowing in one direction to a single device, PCI Express x4 will give
> better performance if multiple devices are in use at once or if
> communications with a single device are bidirectional.

Genial, no me enteré de mucho.
La pregunta sería, si me comprase un pc ahora,

¿Qué es lo que me van a ofrecer de forma estándar?

¿En qué cosas me tendría que fijar?

¿Se venden placas con los tres tipos de PCI? ¿O el pci de toda la vida
ya está anticuado?

Los agujeros negros son lugares donde dios dividió por cero.

Black holes are places where god divided by zero.
