Do I Need A Crossfire Or Am I Doing Something wrong?

[AoCFacePlant]

I currently have 2 gtx 980ti and i am also running a msi b-150 gaming m3 motherboard with a i7 6700k cpu. I noticed my computer not working to its full potential after switching cpus and i realized after checking nvidia control panel that my sli isnt working anymore. I did research and i've seen that you need a crossfire bridge and i'd rather not go buy one and it still not work.

I believe that board only supports Crossfire, not SLI.

You forgot to mention that GTX 980ti's are NVIDIA so they SLI, they don't crossfire.

Exactly, that board does not support SLI, so that's why you aren't getting any performance gains from the second card. You should get another motherboard that actually support SLI, and then you'd also need an SLI bridge, though the normal ones should be fine, you don't need any of these expensive HB bridges, unless you are planning to run games in 4k. And you usually get a bridge bundled with most SLI compatible motherboards too.
