I'm using the 920 card with DTN and UMDS. I hadn't realized it before, but I
can now see that I was missing several thousand trades and quote changes a
day. Running DTN at 460K with the 920 card and UMDS has increased my trade
count significantly, and I assume the bid/ask quote changes even more
dramatically.
