The problem is probably tied to the new precision.

Yes, it would be annoying taking 3 seconds to enable and disable, or you can just watch the frame drop. It is the decision you would have to make.

I also know what K Boost is, as I use it for benchmarks, and find it very easy to use through precision 4.2.1, and that requires opening an extra menu unlike 5.0.0.

Can you answer the question of what happens when you enable it? You said you couldn't get it to work, so this picture didn't answer the question.

I will see if I can find 5.0.0 or 5.0.1 tomorrow and look at it.

So, the option is grayed out and not doing anything? You shouldn't need the enable overvolting to get K Boost to work, as far as I know.

I have it downloaded on my hard drive. I waited to see how it all turned out, and quickly realized that there were issues that I didn't want on my computer, so I never loaded it.

You may want to hop into the precision x15 thread, and search it to see if there are known issues with K Boost, as this is going to be the best way to get your games to perform steady. Yes, it may be a little annoying to enable and disable it, but if the frame drops bother you, then taking the same amount of time (with a working K Boost feature) to enable it once and then disable it will alleviate the issue, and you can enjoy the games you want to play.

Like I said, I will load it tonight and see if I can get it to work. Until then, please look through the other thread to make sure it isn't a known issue. I am on mobile, and searching is not user friendly on a phone.

Run a custom vBIOS that disables the boost on the card. Problem solved. 

Wouldn't that cause trouble regarding the warranty?

As far as I know, both models of the GTX 780Ti SC are single BIOS.

It's not hard to do at all. What vBIOS are you currently running on your two 780 Ti's? You can view the vBIOS version by running GPU-Z. e.g. 80.80.34.00.80 or 80.80.30.00.80.

According to GPU-Z I am running vBIOS 80.80.34.00.80
 

Is that for both cards? If so, here is how to flash the cards...
 
#1 Backup both cards original vBIOSes.
- Backup your original vBIOSes to a folder of your choosing using GPU-Z's .rom backup feature (circled in red), make sure to backup each vBIOS for each GPU on the GPU-Z GPU list before flashing the new custom vBIOS. (circled in red.)

NOTE: If you can't get GPU-Z to backup your original vBIOSes keep trying older versions of GPU-Z until you find one that will allow you to backup both vBIOSes. You can find older versions here. To view all the older versions change "show latest versions" to "show all versions" at the top right of the page.
 
#2 Download NVFlash v5.165 to your desktop.
#3 Right click NVFlash v5.165.zip located on the desktop and select "Extract to nvflash_windows_5.165\, a folder will be created on your desktop named "nvflash_windows_5.165" for you. You must have winrar installed to do the extraction like i'm describing. Winrar can be downloaded here.
#4 Download the custom vBIOS here to your desktop.
 
Flashing Procedure for Multiple Cards: (Flash one card at a time to prevent issues. DO NOT FLASH ALL CARDS AT THE SAME TIME.) 
#1 Move the "skyn3t-780Ti-SC-ACX.34.rom" vBIOS into the nvflash_windows_5.165 folder via drag and drop.
#2 Open Command Prompt. 
- Windows 7: Press the start button and type "cmd" without quotes into the search feature bar and hit enter. 
- Windows 8: Press the Windows Key & X keys togeather and select Command Prompt from the menu. 
#3 Type the following commands into the command prompt... "cd desktop\nvflash_windows_5.165" without quotes and hit enter. 
- Type "nvflash --index=0 --protectoff" without quotes and hit enter. (Turns off write protection on card #1. Some cards will need to have this disabled before you can flash the card so always perform this command before flashing.) 
- Type "nvflash --index=0 -4 -5 -6 skyn3t-780Ti-SC-ACX.34.rom" without quotes and hit enter. (This will flash card #1.) 
#4 If you get an error stating "Firmware image PCI Subsystem ID <xxxx.xxxx> does not match adapter PCI Subsystem ID <xxxx.xxxx>" just ignore the error (this error will cause no harm, it's just letting you know you are changing the subvendor on the card from EVGA to NVIDIA.) and continue on flashing by pressing "Y" to override the error. nvflash should now start to flash your VBIOS to the modded VBIOS and complete by saying the flash was succsessful. 
#5 Restart PC. (NVIDIA drivers should automatically detect and install the card, if not, you may need to uninstall the drivers and re-install them.) 
#6 Open precision x or msi afterburner and check to see if your card has been flashed by checking the power target. (Power target should be able to max out at 200%.) 
#7 Perform steps #2 through #6 until you have succsessfully flashed all cards. Don't forget to change --index=0 to --index=1,2, or 3 to flash cards 2,3, or 4.

The vBIOS should do the job.

No adjustments needed inside precision x unless your overclocking. Try installing driver 331.82, make sure to do a custom advanced install, uncheck all options but physx, check mark perform a clean install. Report back with your results with driver 331.82 installed.

Sajin
#1 Uninstall whatever version of MSI Afterburner or EVGA Precision X you're currently running.
- Select "no" to saving profiles if asked.
#2 Uninstall all nvidia software & drivers from add/remove programs.
#3 Reboot the PC.
#4 Install driver 332.21
#5 Install EVGA Precision X v4.2.1. You can get it here.
#6 Enable K-Boost inside Precision X.
#7 Reboot PC.
#8 Verify your clocks are running at max inside precision x.
#9 Test to see if you're still getting micro lags.
