Most likely, you have both. The K8T800 (or similar) is essentially what
was left of the north bridge after the DRAM controller was moved into the
CPU. So, it connects the processor's HyperTransport to the AGP slot
and to the V-Link to the VT8237 (or similar) south bridge, which in turn
connects to all the rest of it (PCI, LPC, SMBus, ...)

The datasheets for both (as bad as they are) should make the general
architecture pretty clear.
