So I have a new rig that can run Skyrim on Ultra. My old one could only run Skyrim at 25 fps and that was on low, so I never bothered with graphical mods. It's a laptop, and here are the specs:

i7-3610qm
AMD Radeon HD 7970m
8gb 2x4gb ddr5 1600mhz
750gb 7200rpm

I get 50-65 fps on average, depending on where I am. So I have one question, what would be the best graphical mod that would still be able to keep me above 35fps?

Thank you
