No, it is ok, you can run concBandwidthTest.exe 0 1 to see how PCI-E is saturated, it should show over 20000MB/s if you have good motherboard and cpu, which can use both card simultaneously with full speed PCI-E throughput. Only let down is that Titan does not support concurrent bidirectional transfer, but anyway I suppose no application supports it and it would be difficult to optimize algorithms to fully exploit this feature.

On X79 you have to enable ("hack") PCI-E 3.0 in your registry.
It looks as though perhaps you have not done this.
here is a link with instuctions, if you have not and are interested

I don'y have enough posts yet to link direct, so...

I have had the 3.0 hack enabled, thing is I didn't do 0 1, I just did each card individually (I think). Here we are,

Which is pretty damn fast, in the original thread there is e.g. x58 result which has total pcie bandwidth with 2 or 3 gpus similar as with one gpu (so x58 was "faked"). Now with x79 and appropriate cpu one card reaches 11000MB/s (which is slower than x87 where I have 12000MB/s, but it is not big difference) and two cards 22000MB/s which is impressive number and not faked chipset or cpu.

Mine is about 1/4 of what you guys are getting, but I am on PCI-E 2.0, I assume that's why.

If you tested bandwidth with one card then the reason is PCI-E 2.0 and fact that you tested with one card.
