Just responding to the argument that a 1.6Ghz i7 processor is too slow for Skyrim.
I know little or nothing about the technicalities of processoers but I too play Skyrim on a laptop with an i7 720m processor, same one as Nirrtix, I have a stronger GPU though GTX 280m, but only 4Gb of RAM. I play at 1920 x 1080 resolution.
I play Skyrim on high settings, with a few of the distance sliders nudged up, but AA switched off and replaced by FXAA, 16 x AF. Some texture replacers (rocks, ice). I get 40-50 FPS outdoors and 50-60 FPS indoors using Skyboost version 3. FPS from the top of the steps at Whiterun, looking at the big tree is around 33.
Clearly my 1.6Ghz processor is not holding back my game.
Thanks for posting that, as I said... I think something else is at play here that's not related to his RAM or the CPU... are you running 64bit or 32bit windows? Since he has more than 4GB RAM, there could be an issue with the patch and 64bit windows. But I'm thinking there is something going on with his PC which is more likely.
The truth is most people that are having issues that are above spec, are likley are not taking proper PC care or are having some hardware/software related issue...
