Mine came today. It only took two days to get from PA to MI and that was with the FREE shipping option. I feel sorry for the folks who paid extra for two-day air.
Man, this thing is HUGE. I had to move my IDE hard drives from the slots they were in when I had SLIed 7900GTs to the bottom of the case to make room for the card and the power connector. They really need to place the connector on the edge facing out and not the end of the card.
Still tweaking and testing, so I can't definitively rule on it, but it seems faster and smoother. I'm able to turn everything on full blast in FEAR - 1600 x 1200, 2X AA, 16X AF, and soft shadows(!!) and get ~70% over 40 fps. STALKER also runs smoothly for the first time. I'll post back more when I've got a better read on things.
