Basically you guys be lieeeeeeeeeeeeein. I have the rig to poove it. I could easily afford two more 580s but really its just not worth it for any game on the market lol.
I don't know about anyone else.....
but i'm not lieing...
I could easily shove a bunch of video cards in my rig... oh wait i did that already..
Currently the games limited to working properly with the best overall performance with only one video card.... OR with only one GPU (dual gpu cards are essentially sli/crossfire in a card and also do not work well)
The game is HEAVILY CPU dependant.... I've learnt that from the range of video cards and machine I've got.
While your using a fairly good system, i can easily claim mine is equivalent in some cases and far superior in other aspects... but i'm not here to show off my e-[censored].... lol
If you must know i'll devulge....

Using the LAA Fix on Skyrim allowing it full access to 4GB of ram
Set ULTRA settings using the launchers options, saved exited, modified the INI with resolution and heavily modified for higher quality/increased clouds and tree/foliage range, increased cell grid and maximized the buffer and memory to their suggested maximum.
Using 2x FSAA, NOT using FXAA, NOT using Floatingpointrendertarget (this option increases level of detail in shader effects, however at a huge HUGE massive cost to frame rate even on top of the line cards...). additionally FPS limit is set to 0 to prevent fps locking or limiter
V-SYNC disabled, no 3rd party programs used to effect crossfire/profiles/3d settings in any manner using default CCC settings....
Averaging about 30fps with the single ATI Radeon HD5770 @ 3240x1920
Highs in the 60fps (rare.... usually don't see anything higher than 35-40fps) with lows in the 20fps range (rarer for below 25)
Using the Crossfire quick key trick (which only works temporarily) results in a sustained 30fps regardless of where i go, seeing averages in and around the 40-50fps mark highest exceeding 60fps (managed 120fps in a few cases)
Enabling uGridstoLoad 11 results in a sustained 20fps
