I would have hoped that a card of this size and power would have an onboard physics processor.... Maybe next-gen cards will
Edit: They're also doing away with the GTX surname, it's now back to GTS and GT. So this card shown here is actually an 8800GTS, not GTX
Edit 2 @ WC: I would imagine that extra chipset on the left is to manage the extra 128bit memory interface since they've now gone from 256bit to 384bit. That's just my reconning however, thanks to NoL's advice.
