ATI asks for a third PCIe slot

THE WIERDEST BIT of news comes to us from no less than three mobo makers at Computex, and it concerns ATI.
The whispers are that ATI is now asking mobo makers to make their high-end boards with slots for three 16x GPUs. All three slots may not need to have a full 16 lanes routed to them, 4 or 8 may work out fine, but the slot physically must be 16x.

If you are going to go Crossfire, at least two would need to be 16x. I wonder what they want the third card for? µ

That's what The Inq says, I predict that the last 16x slot has something to do with physics, so that users could still run Crossfire and have a separate graphic card do physics.
