I didn't see the first part of this thread, and was wondering if
you're also using the ASUS utilities that came with the card. I
think they may interfere with TT, or vice versa, the same way that
running CCC wouldn't be good with TT. I have been using TT forever
and never had a problem, but have not used it in my newer machine,
which has the same ASUS card as yours. It was hard enough just
getting drivers to work with the damn thing when it came out. But
since it's been working, it's a great card.
