PCI Express vs AGP 8X ?

Specs: Win XP Home, P4 2.4 512 DDR RAM

I was wondering. Is PCI Express really far and away better than AGP 8X? What's the bus speed of PCI express? Is it 33mhz?
The mainboards I've been looking at on the internet with PCI express don't have AGP slots.
Is there some reason why PCI express cannot coexist with AGP?
Thank you in advance for your replies.
If you know of any good informative reads on the net about this subject. Please let me know.

PCI express with its sixteen pairs carries 4GB/s as opposed to AGP 8X 2.1 GB/s.

For peripheral devices, a single PCIe line carries 200MBs, somewhat faster than the total PCI throughput of 133MBs.

"Is there some reason why PCI express cannot coexist with AGP?"

It can. ECS sells a ECS 915P-A motherboard with pci express 16x and agp 8x along with pci express 1x and with DDR and DDR2.

GIGBYTE has a motherboard like ECS, but it has a G.E.A.R. slot instead of a full agp slot. You can put an some AGP's in a G.E.A.R. slot but it is only good for temporary use because GIGBYTE claims that it can shorten the life span of an AGP card.
