So I've been having a problem with my Y580 dropping framerate during gaming (Borderlands 2 and Torchlight 2). The game would run fine at a nice 60 fps, then suddenly drop to 30 fps for a second or two, then go right back to 60 fps. This is getting really annoying, and happens very frequently.
FYI, I'm on Windows 7 x64, and using Nvidia driver 310.70
Here is a video demonstrating the problem: http://youtu.be/pyuvk9w4jMg

I'm 100% sure this is caused by vsync. Vysnc prevents screen tearing, but it has the side effect of only being able to run a game at 60fps or 30fps. If performance drops under 60fps even slightly, the frame rape drops to 30fps. Try disabling it in the ingame settings.
If you like vsync because it prevents screen tearing, enable it in the nvidia control panel (manage 3d settings -> program settings -> select your game) and make sure triple buffering is on. This prevents the sudden frame drops Nvidia also has a new feature called adaptive vsync which also solves the problem. Make sure your graphics driver is udpated.

Can you monitor your CPU frequency on a log file while gaming. On my Y470, when Intel Turbo Boost gets turned off and on by the BIOS CPU temp setpoint of 85 - 90 oC, I get those sudden FPS drops. Like others said, it could be v-sync since I get 80 - 110 FPS on max settings without v-sync on Torchlight 2, and I never gotten those FPS drops with v-sync off even on heavy boss battles with lots of spells and light effects.
