Got it today. Installed it tonight. Weird thing: on the reboot for both the removal of the existing driver and the install for the new one, my computer hung during the shutdown process and I had to do a force shutdown. Everything seems to be ok though. Still a little laggy on High with Bad Company 2 but much better than my old card.
I don't notice any noise difference between this card and the previous one.
OH, and sidenote, the video was locked up on the old card when I came into my office to replace it.
