It depends on what you are sending over the bus.  AGP was designed to
rapidly access system memory so that it could be used for graphics
memory.  Having a lot of memory on the video board tends to negate this
need.  We could use 64 bit @ 66 MHz.

If you do AGP you also need AGP port support.

It depends.  An AGP port can also function as a PCI port if we don't
need the rapid system memory access.

PCI-express needs the PCI-express way of mapping VRAM into the CPU/GPU
address spaces.

Is there a method that PCIe uses to access system memory that is
different from PCI?  That is, does it have some method like AGP?
