So after a few days with this card, and working under headphones so as not to disturb my wife, I am noticing a low level "sizzle" that seems to be attributed to the video card in some way. When I move the mouse around I can hear it "zipping". A quick search on the internet indicates this is not uncommon, and may be attributed to the USB bus, although the term "noise" seems to include ground hum type of noise which I am not experiencing.
Any thoughts on this?
