16x PCIe 1.0 should be plenty fast enough.

I did see some comments in one of the other threads mentioned above that
suggested that heat may be an issue.  Apparently the cards will clock down
when they get hot.  Because you seemed to suggest at one point that the
issue appeared resolved, then came back after an hour of use, you might
just check to see how hot the card is getting.

Good luck on this one.
