[Mussyo]

I have an ASUS Z87-A

And i am using 2 gtx 980s in SLI

 

According to the specs of the PCIe slots, is the motherboard bottle necking my FPS performance ?

 

I am getting lower frams on SLI than I am with SLI OFF!!

It should be be fine, do you have the cards plugged into the right slots? Make sure they're both in the 3.0 slots.

I think I do, I will double check, is there anyway you can explain the brackets on this.

 

( 2 x PCIe 3.0/2.0 x16 (x16 or dual x8) )

Just checked, they are definitely in the right slots, the two PCIe 3.0 slots

Have you performed a BIOS update along with all you drivers?

[Mussyo]

I have, but as for the drivers I also updated, BUT!, what i did as a final measure was use a tool to completely remove all previous drivers and files to that nature and reinstalled, and LOW AND BEHOLD, 80FPS!!! thanks for all the help brother, I got exactly what I needed done

That was going to be next suggestions. Video drivers are tricky like that.
