Edit: If you're reading this, it is wrong. Apparently it's because SLI isn't working in the benchmark.

OLD POST
It isn't the video card, it's your CPU. It is severely underclocked.
 
Intel Core i7-4790k
Reported Stock Core Clock: 4000 MHz
Maximum Turbo Core Clock: 815 MHz
 
That Turbo number should be higher than the stock clock. The turbo clock on an unaltered 4790k is 4400 MHz, so you screwed something up in your overclock, are drawing way too much power for your machine, or have some EPU settings locked in for energy savings or something.
 
Here's what mine looks like:
 
Intel Core i5-2500k
Reported Stock Core Clock: 3300 MHz
Maximum Turbo Core Clock: 4400 MHz

SLI is not working properly.  It's only running a single GTX 980.  There's some issues with the new 970's and 980's not working properly in SLI.
 

hi
Thanks for helping me out 
 
Well i followed your instructions and tried to reset my bios and change power settinngs in cotrol panel to performance.
 
And got a firemark score at 11852 
Reported stock core clock 4.000 MHz
Maximum turbo core clock4.397 MHz
 
But for some reason i does not detect my SLI Cards.
I have enabled SLI in NVIDIA control panel, and Precision X 16 detects the cards, and in game it also works but not when running firestrike.
I have tried to run Valley benchmark and it also works with SLI?
 
Any other options i can try ? 

I have now tried to run Crysis 3 first with SLI disabled in Nvidia controlpanel, and then with SLI enabled. 
As you can see the FPS is almost 2x higher with SLI
