Although AGP isn’t yet a dead technology for graphics cards,
it’s rapidly moving on to the endangered list as PCI Express
grows in popularity. Motherboards that support PCI Express have
a large chunk of data bandwidth assigned to this new bus which
is usually divided up into 20 lanes.  Of these 20 lanes, 16 are
dedicated to a slot for a PCI Express 16x graphics card, or
PCI-E 16x for short, and there will also be one or two short
PCI-E 1x slots. Although we have yet to see expansion cards that
use PCI-E, other than graphics cards, you can be sure that they
will start to make an appearance during this year.  Athlon 64
and Pentium 4 motherboards that support PCI Express also have
conventional PCI slots but you will usually have to choose
between AGP or PCI Express graphics as very few motherboards
support both types of graphics.  The real strength of PCI
Express is that it has a huge capacity
