Yeah, you want to disable SLI for folding.
 

Did you enter a passkey?
Try adding the client-type advanced flag on your 680's.
Configure> Slots> GPU> Edit> Extra slot options> Add> Name: client-type Value: advanced

Welcome to fold.
Try and apply the above advice and I believe you still need to complete 10 work units with a passkey to receive the bonus. (QRB) Until then your points will seem mediocre.
 
Edit: I might add to finish the cpu wu and concentrate on the gpu's until you get them running smoothly. They will be the meat and potato's of your point accumulation.

Did you follow tucker's advice with the configuration and click save? (I always forget to save) Do you have a passkey? You need it.
Your stats so far. 3 down, 7 to go. http://folding.extremeoverclocking.com/user_summary.php?s=&u=660716

Yeah, I clicked save but it made no difference. Maybe I have to do that both of my GPU? I have a passkey and entered it. I'll let it run tomorrow for a while and see what I get. An ETA of 10 days seems like a long time to me for my second GPU. My first GPU dropped from 5 days to 12 hours after about 45 minutes. Those 3 WU must have been from the run that my CPU completed.

Yes, do it for both.
Give it 30mins or so and the eta should drop to where the first one is at.

I'll give it a try and let it run for a few hours tonight.

There's also the driver issues.  For whatever reason, something in Nvidia's drivers after 327.23 crippled folding performance in GK104 cards, i.e. every 600 and 700 series GPU except the 780, 780 Ti, Titan, and Titan Black.  Stanford has introduced a workaround, but it's still in beta testing.  The magnitude of this issue is somewhere around 70% lower PPD.
 
So, you have two options.  One is to roll back to 327.23.  The other is to leave the drivers alone and change your GPU slots to client-type:beta instead of client-type:advanced as shown in tucker147's post.  You should get the version of the beta core with the fix; it's version 0.0.55.  The core version shows up in the log file like this:

22:52:41:WU00:FS00:0x17:Reading tar file system.xml

22:52:41:WU00:FS00:0x17:Folding@home GPU core17
22:52:41:WU00:FS00:0x17:Version 0.0.52

 
(I'm on client-type:advanced and running version 0.0.52 since I have 780s)
 
Now, using the beta flag can be a bit more problematic.  Anyone can use it, but if you want help from the official folding forum when running it, you have to also be a member of the beta team.  There's a beta testing section of their forum that's read-only if you're not part of the beta team, and if you post about issues outside of that forum and they see you're running the beta flag, the mods will just tell you to remove it and re-post once you've encountered your issue without the flag.  This isn't a major problem, as most issues can be resolved by other EVGA members here, where there is no such proscription.
 
The bigger problem with using the beta flag is that you will get WUs from beta projects at some point in time, and something will invariably go wrong.  Projects that have just been released to beta sometimes have PPD issues (usually too low, but sometimes too high), will have bad WUs that crash and get you no points, etc.  Part of joining the beta team consists of accepting that these things will happen that you are okay with not earning top PPD because you'd rather help work out the bugs.  If you're not part of the beta team but are running the beta flag, you get the sporadic issues and occasional temporary benefits (such as access to this fixed core before it's released to the general public) without being able to provide feedback.

I installed the 327.23 drivers but I also lost the SLI option in my Control Panel. I got an Event Viewer error 14 "Device not found" and when I rebooted from a black screen lockup it installed the newest WHQL. Any driver older than 335.50 loses my SLI function. I tried using that driver when I first upgraded to this Z97 and it wouldn't install properly. I am seeing an increase but my second GPU is basically useless. Both boards are running at 1215 MHz. GPU-1 ETA dropped to 1.17 days. "Points per Day" box is well over 130,000 now. Here is a screenshot:

That's rather unusual.  Might be redundant, but have you tried doing a clean installation of it at any point?

Also, you might try 326.80 beta.  It was the release right before 327.23 and I don't think there were any issues with it, either folding or non-folding.

This was fresh install of Windows 7 and right off the bat I had no SLI option when installing these drivers. I was stuck using the 337.88 WHQL. Whenever I feel like playing any games I'll either have to change my drivers or play with a single GPU or just forget about folding all together. Maybe I'll put in a support ticket and see what kind of hoops EVGA support wants me to jump through. In the mean time I'll try swapping SLI bridges (makes no sense since other drivers work) and swapping slots. Thanks for all of the help and advice.
 
BTW I just noticed a new WHQL release version 340.52 available at nVidia.com. After I get a baseline I might give these a try. Hopefully my SLI comes back.

If you do come out of retirement, have you tried folding without the CPU? When I have issues with a new folding setup, I try to turn things on in stages. One GPU let it get to the correct PPD, then 2, then the CPU if I am doing that as well. This can point to where the issue arrives. It can take a lot of time to get sorted, but you don't have to be at the computer the entire time. BSODs are certainly annoying, and to me would point to a driver issue or a failing hardware.

Right click on the cpu in folding slots and select finish. That way it won't get a new one when your done. Then go into Configure>Slots and highlight the cpu and Click remove. You can add it back when your ready.
Good luck Zuhl3156!

If I recall correctly, judging by your cards you'll want the latest beta core anyway, since it had the fix for the GK104 folding PPD... IIRC.

I may not.

Ay Zuhl!
Since you are one of those who wants to do good, and before you throw in the towel due to too much hazzle, have you checked out Crunching?
As my sig indicates, I've done some folding too, but lately I've moved more or less over to Crunching. ( Folded a bit last week)
Here you have a whole different freedom to choose what kind of project you want to support. Cancer, bio-medical, astronomy etc etc.
You can also choose freely among GPU and/ or CPU work.
I crunch on a wide variety of computers and GPU's. From old Two core Win XP machines, to OC'ed i7's, and from GTX210 to 780Ti Classy's.
The BOINC client we use for crunching never caused any issues, on any machine.
You will also have the opportunity to get a much better insight in the different projects.
Also, our team, [link=mailto:crunching@EVGA]crunching@EVGA[/link], are the greatest guy's
Just posting this to be certain you didn't miss this option.
 
I hope your neck is better
Take care
