Here's a video of a 480 running furmark with spitfire... I had no idea you could take the metal plate off... is that safe? O_o But damn that's staying frosty.http://www.youtube.com/watch?v=nMxWVgYRv-M
EDIT: I just noticed that his PSU isn't mounted on bottom, which wouldn't work for me. There's a huge fan there.
