I have a 3570k @ 4.0ghz so it's not a bottleneck. I've never had any FPS issues before in it but lately when I go into caves there are points where i have 0-10 FPS and it is unplayable. I put up the MSI Afterburner GPU monitor and I noticed that when it happens my GPU usage is dropping to 0-20%. This all fixes itself when I go back into open world where I get 80-90FPS and 110-144 in buildings. I don't have any dungeon/cave specific mods installed. I've re installed drivers and switched PCI slots. This only happens in Skyrim. Any ideas what this is happening?

Firstly to start off, a 3570k at stock clocks will not bottleneck a 660ti. As far as I can see you can try reinstalling the game and see if that helps. Just save a copy of your save file then once the game is reinstalled, put your save file back into the game files.
 
Check the clocks. I'm guessing your card is dropping to 2D clocks for some reason. I had that problem in Guild Wars 2 on AMD cards, and I've read of other people having similar issues with various cards in various games. You may need to force 3D clocks.
 
I think this may be related to video memory usage.
I have been running some benchmarks and Skyrim manages to use all 2GB of video memory on my GTX 770.
This is likely associated with the mods I have loaded, including high res textures.
Some tips to reduce memory usage without sacrificing quality:

1. This is a Windows 7 setting to disable fancy desktop features while running Skyrim.
Right hand click the shortcut you use to start Skyrim (probably to skse_loader.exe if you are running mods).
Click "Compatibility"
Tick "Disable visual themes" and "Disable desktop composition".
Click OK

2. Reduce antialiasing in the Skyrim options from 8 samples to 4 samples.
