I bought a new mobo late last year to go with an AMD 4000. I already
had an X800 Pro, AGP, so I didnt feel like going PCI Express at the
time (and they were brand new) and having to get a new GFX card.

Well, now I want a 7800 but it seems like they are PCI-X only?

There are no PCI-X Geforce cards. You probably mean PCI Express which
is appreviated "PCIe". PCI-X is something different (enhancement of the
old PCI bus, usually used in servers and workstations for NICS,
FC-Controller and SCSI/SATA HBAs)...
