I purchased this board and plan on adding my 2 560 ti 448 Classified cards in this weekend. Just have a question, which slot do I use for the second card?
 
The board came with an SLI bridge, which is long enough to reach from the top PCIe slot and the bottom PCIe slot, which is how I would think it connects. Now I understand that when 1 card is installed it is x16, 2 cards it will be x8. The 3rd slot on this board is x4 used for Physx. Each slot on this board are labeled, the top being x16/x8, the mid x8 and the bottom slot (black) x4.
 
This would leave me to believe that the top and mid slots should be used in SLI, and the bottom slot for Physx, but why would the SLI bridge be so long and I do not think that 2 of todays cards will fit in this fashion, they are just too large. I would hope I can use the top and bottom slots. Any help is appreciated.
 
Attached is a close up of a shot from Newegg showing the top and bottom as PCIe 16
 
 
 

I figured it would be, I should have looked closer before buying, plus now it is on sale for even cheaper. I suppose the SLI bridge will have a bend in it with the cards being this close.
 
Anyone put two cards on this board yet?

I have the P67, basically the same, with two 580's. My HAF tower through plenty of air at it. I did not like the spacing at first but I get great temps, all out and cranked up in BF3. 
 
My temps run in the high 50's under load.
