I know there are at least a few rattling around, as they were shown at trade shows and some sources benched them. The 6000 seems like a bit of a white elephant now, but it would probably provide excellent performance (assuming you are one of the lucky few who can fit it inside your case) and bragging rights for at least the next few months or so. Tough to get worked up about its feature set with the GF3 right around the corner.
