On my own, I took the decision for a (powerfull) Notebook-desktopreplacement , even when it seems to be more expensive first, but runnig/effording two PCs (NB&Desktop+Monitor)isn't that realy cheap . You see my Specs down here, but as far as I know ist the Nvidea gtx485m that I use more powerfull than the gtx560m.
What can you do with it? Well, in the 1920x1080 Fullscreen resolution my settings are
Epi filter, SSAO off, Vysnc on. Anitalaising 8x, (even there's no effect)
Model text high, Buildingtext high; Landscape-Textures high /Textquality middle, Forest low, Effects middle, Damage high
landscapeshading middle, buildingnumber unlimited. Grass, Splins, Shadows on
Your fps are depending where you fly and on which altidude, I can get 20 to 60 fps, but with the 1.0042660???patch it was better.
I found out that clouds, build in the FMB by the weatheroption can seriously bringing down your frames,
See this f.ex. taken by 1024x768 frontprojection-res, (Normaly I would get 80fps there)
Unfortenatly only one of my cores is realy used, also only 1500 instead of the 2000mb graphic memory. But I am also hoping for performance improvements by the developers, espescially the stuttering over industrial areas isn't nice
I am fine with my NB, it gives also space to my homecockpit :-) show us your homecockpit
Hope this helps
