All,

Johnathan's reply in this morning's digest triggered a thought, so I 
went out and googled "PCI-E latency" and came up with information
that was new (to me, at least).  According to information here:
    http://downloads.guru3d.com/download.php?det=951
and here:
    http://forum.cakewalk.com/tm.asp?m=1064501&mpage=1&key=􄇄
PCI-E doesn't take latency settings because each card has a (separate?) serial
connection to the system rather than a shared bus.  Hence, PCI-E connected
resources show zero (0) for their latency when PCI configuration tools query
them.

Make sense?  Original question answered?

Craig
