  1. Back when I had Origin’s tri-Titan equipped Genesis in house, I received a few requests for benchmarks with PCIe 3 enabled. Because we tested the system with its default out of the box settings, the system was configured by default...

    PCIe 3.0 doesnt seem to improve anything with 1-2 GPUs. I think they should have tested 3 way SLI to confirm this.

    Didn't they say it was impossible to use more than one full PCIe 3.0 in that configuration? They delayed publishing anything because they couldn't accomplish this.

    Depends which board you're working with. Not all X79's are created equal.

    Although I think you'll find that registry hacks don't figure in HWBot's submissions, so until the X79 chipset is actually qualified for PCI-E 3.0 (by Intel), most quad setups (being benchmark orientated) would likely feature PCI-E 2.0.

    For tri-SLI there is actually a non-hack option available. The Gigabyte X79S-UP5, despite the name, is an Intel server chipset (C606) which is qualified for PCI-E 3.0, as are the Xeon E5's the board is compatible with.
