I have the top end 15inch and I just wanted to share how well Skyrim runs. At 1440x900 res I am able to have texture quality on ultra with the bethesda hd textures and skyrim 2k textures. For antialiasing I use sweetFx with smaa as the quality is just as good with almost no performance cost. For anistropic filtering I use Nvidia inspector. Also I have Sharpshooters ENB on (go check it out, it's by far the best ENB I have used so far) with bloom, bokeh dof and medium-high SSAO. And on top of that I have a crapload of other graphics mods including: Lush grass, lush trees, enhanced distant terrain, realistic lighting ,8k rocks, climates of tamriel, pure waters and amidianborn book of silence. With all this on I am still able to get playable framerates! But my graphics card is overclocked to 1040mhz core speed though(better than gtx660m and almost gtx670m. 3Dmark score is over 2800.)
