Call of Duty: Advanced Warfare in multiplayer. Sometimes it would dip into the 80FPS range... but it wasn't a whole lot. I'm not really sure what was causing it.
I was having issues with the cards. I did some troubleshooting, it was definitely an issue with SLI. If I had the SLI bridge on the slot closest to the back of the card, they would have black line across the screen during benchmarks and a little bit during my call of duty sessions. When I switched the bridge to the other set, it seemed to fix the black lines. It could have been a rare situation, but I got so frustrated I just returned them. We'll see what February has to offer... TBH, i'm hoping AMD releases their new generation of video cards as rumors have been mentioning.
