frame issue with 980Ti in sli (not resolved)

my problem still remains but my previous post was moved to resolved when in fact it wasnt resolved and i wasnt contacted to try and fix the issue.

during dungeon runs i see fps around 144 but during fights ill see it drop to 70-80fps. once fight is over or if i look away from boss the fps goes back up. im also playing this game on 3 monitors in which each are at 144hz. im also using evga precision x to monitor gpu temps. the first card is at 83 degrees celicus and the other is at 62 degrees celicus. seems kind of high to me. both are only using 2672 mb of vram as well.

system spec
i7 4790k
x2 980Ti (sli)
16gig ram
win7

Hard to say if there is even an issue. FPS min/max can be a pretty large range. In fights you are probably limited by CPU processing even though the GPUs have lots of headroom.
