Well I don't really want to OC my GPU until I feel it just isn't up to par with the competition anymore (basically when I start considering an upgrade) so that's really not too much of a contributing factor for me. Also, yes I definitely agree that it is a pretty insane deal considering (as you mentioned) even some 7850s are more expensive!
However, the fact that it requires two 6-pin power connectors is a REAL turn off. At this point I think I can probably just hold off. I hate to pass up such a good deal, but I'm just not sure if it's the right deal for me.
