tesla S1070 connected to an "evga SR2 / SRX classified"

hello,
i looking for a mother board in order to connect a tesla s1070. I wana be able to connect the 4 c1060 to the same mother board with the hic + 2 video cards in sli.
I take a look to High Performance Supercomputing | NVIDIA Data Center GPUs almost workstation mobo from asus or asrock External Image are not be able to do this without bottleneck (not enought real 16x) and tyan is not for me because i looking for a mother board for workstation not a server one.
So i have found the evga “evga SR2 classified” socket 1366 who seems to have a four true 16x pcie gen2 http://www.evga.com/products/pdf/270-WS-W555.pdf.

I have questions :

  • Does somebody has an s1070 with 2 HIC + 1 or 2 gtx (sli) connect on the same sr2 evga ?

  • Does it work correctly.

  • What 's about the bottleneck ?
    -As the evga mobo sr2 seems to be the only one to have four real pcie gen2x + sli, would nividia be able to test it and add it to “the build your own” if it’is compliant ? I am not the only one to ask myself about it ! The evga seems to be a good compromise.

  • Would nvidia be able to do the same with the sr2 succesor sr3/srx EVGA SR3 Super Record 3 Motherboard Pictured | TechPowerUp as soon it will arrive this winter ?

thanks for your help !!
