I'm eyein' the 6850 - however I like the 6870 as well. I think that would be just a bit too far out of my power envelope. I could justify the 6850 though cause not only is the idle draw way low, but so is the load. And it'd be a nice, *very* nce, performance boost over my current 5770- which I'm already satisfied with.
Think I'll wait a few weeks and see what inventory/prices do. But likely, I'll be having my self a 6850 before too long.
