So my combo Christmas/Birthday gift (my birthday is the 26th) is coming soon. For Christmas, I'm getting this to replace my nearly 6yr. old Radeon HD 6870s.

So now my PC will stand at this:

Win. 8.1 x64

Intel i7

12GB RAM

Skyrim loaded from SSD

And that GPU linked up there^

So I'm getting ready by re-downloading Skyrim, re-installing my gameplay mods etc. However, because my old GPU could only semi-handle the original Skyrim, I never really got to use any appearance mods other than W.A.T.E.R and a couple of character model touch-ups. So I'm asking here; with my new set-up, what kind of graphics and improvement mods would be recommended to make Skyrim look the best it can be, while still keeping a stable game and good FPS?
