Just to complete the story. The full family is together now.

10.752 CUDA cores
24 GB GDDR5 RAM,
> 1 TB/sec aggregated memory bandwidth (in the cards)
ca. 6 TFlop/s (double precision), ca. 18 TFlop/s (SP) -
(This is roughly comparable to the #1 position of the Top500 list in 2000, the ASCII White machine for approx 110 million US$)

When PCI 3.0 support is turned on, each card can read/write with about 11 GB/sec on the PCI bus.
For full concurrent PCI bandwidth of all 4 cards, a dual socket SB machine is needed with its 80 PCI lanes and better main memory bandwidth
(With 1600 MHz DDR3, my dual socket SB delivers ca. 80 GB/sec with the stream benchmark)

So, depending on the GPU workload, a LGA 2011 system might be ok (when compute / device memory bound) or a dual-SB board is needed when I/O bound.
