Increasing the PCI bus to 3.0 does help.  I am running a X79 mobo with 3960x and running the NVIDIA patch to take it to 3.0 ups performance 10-15% Folding.  At 2.0 my cards in GPUZ where each at eating 49-51 percent of the PCI bus.  Going to 3 they are now at 26-30% each.

 
ya, the 1070 is pulling a constant 35% on the bus and after 9 completed units i am at 11% improvement. so it seems that i'll be replacing that data on my first post with this new run once i get a few more units completed.

What cpu are you driving the rig with?  I've done some experiments on a 970 & 980ti on PCIe 1,2 and 3 and have only seen 6% improvements at most, but I'm wondering if my slow cpu is bottling the cards a bit.

i have an older i7-3930K but this thing still packs a hard kick in the performance category. i find it funny how there is still very little gains made in the last few generations of CPU's. but even its avg load is ~12% and can peak around 20%.
 
also, after 15 units the avg improvement is 10%. this increases the 1070's points per watt to 4,196 and the point to USD spent to 1,430. the points per watt is still behind the 1080 by 5.5% but the points per USD spent is a good bit higher than the 1080 now by 16.8%. i'll update my first post after work today.

HAY, i can finally use the forums again! so what i meant to post yesterday is now on the main post. for simplicity i'll put the stuff here too so you dont have to go back.
 
 
OK, first off my initial testing was off by nearly 10%, 569,252 vs 634,077, because i found out that even though all my hardware was pcie 3.0 compliant the gpu was actually running pcie 2.0 until i forced it to run at 3.0 speeds. if you want a direct unit to unit comparison of pcie 2.0 vs pcie 3.0 look below.
 
PCIE 3.0
9704: 636,693 
9704: 644,790 
9704: 645,873 
9704: 638,934 
9704: 648,603 
Avg PPD: 642,978
 
PCIE 2.0
9704: 638,585 
9704: 572,532 
9704: 575,073 
9704: 572,382 
Avg PPD: 589,643
 
8.295% improvement with the 1070 going form pcie 2.0 to pcie 3.0.
 
  
Now with the 1070 avg being 634,077 PPD it is 26% lower than that of the 1080. some other useful stats on the 1070 is that its PPD per Watt at 150W full load is 4,227 and its PPD per USD spent is 1,441. On the other hand the 1080 has 4,423 PPD/W and 1,244 PPD/$. with the 1080 achieving 26% higher PPD while only increasing its TDP by 17% to 180 Watts the 1080 wins in efficiency by 5%. BUT it looses in the PPD over cost department! With an increased cost of 48%, $650 vs $440, the 1070 is actually 18% higher in PPD per USD spent.
 
so in conclusion, if efficiency is your goal and cost doesn't matter then the 1080 is the go to folding card right now. but if cost is of concern the 1070's are there to help you out and not break the bank.

Any idea if the 1080 numbers are from a system properly configured for PCIE 3.0?

i would assume so, my system was an old x79 mobo and cpu which was actually a common issue. anyone running newer systems shouldn't have to worry about that. also if you look here there is a 1080 but FTW edition instead of founders which had an avg PPD of 746,414 over a much larger sample of 28 units.

Did not expect to see that much of a difference between PCIe 2.0 and 3.0. I'm running a single GTX 1070 on PCIe 2.0. I typically only fold overnight a few times a week but I seem to float between 600-750k PPD based on the estimates.
 
Any chance you were running PCIe 2.0 x8 before the switch?

nope, GPU-Z said pci-e 2.0 x16 until i went and forced 3.0 following this posts instructions.

Just an FYI - I found my Gigabyte board refused to show PCI-E 3.0 even when I manually forced it, but found this link to an NVidia app specific to X79 for this issue

https://nvidia.custhelp.com/app/answers/detail/a_id/3135/~/geforce-gen3-support-on-x79-platform

Could be worth a shot as well.

It seems that the 1070 FTW was just in Stock... It also seems that one was just ordered under my account... Interesting.
