I thought today's cards don't even use all the x16 bandwidth...so what's left over should be enough for the extra card

I think they're starting to catch up, but for the most part that's true.

...Slots 1 & 3 are x16 speeds, slot 3 is x8 speed. All will accomodate a x16 size card but the middle slot will only run it at x8 speed.

Hahah, if that was the case then the 8800 GTX/Ultra cards wouldn't be able to run in Tri SLI about a year or so ago...

3-way SLI support was introduced not long before the 780i came out. It brought 3-way PCI-e x16 to the table, as opposed to the 680i's 2-way x16 + 1 x8 lane. That, and Yorkfield support. That's about it (as far as I know).

tri-sli has only worked since a short while before 780i came out... as for 7 series, than never supported tri-sli, quad was supported for two 7950gx2's, but was notoriously poor.
