Both of my nForce motherboards (an Asus and a Gigabyte) have a BIOS
adjustment for latency, you might try playing with that in
conjunction with setting values from within the OS (setpci).
Sure sounds like you have all the bases covered though. You mentioned
you changed PSUs, if you simply tried another of the same type that
might not have proven anything, as you might have an inherent problem
and not a "failure". I saw a power supply advertised the other day as
"600-watt power supply for $10.99", I don't think I would risk such a
thing in any machine of mine :-)
Other than that I don't know, let us know when you do get it sorted
out, even if it does require a new MB.
