My PC is loving this Game. Its Intel but i will let some Pics speak for me.

I cant Wait for the MODs . @ that time I will Flag the EXE to use 3.8 Gig by its lonesome, but for now as you can see it is not necessary.

Game is running even better now, I did some tweaks to the INI and have smoother Frames and better Shadows!

I'm running a 2600k at 4ghz and the game's running very smoothly with max 20% usage across the four cores. I don't think CPU bottlenecks are an issue for Skyrim. Failure to utilise CPU resources definitely seems to be a problem for a lot of people. The game seems to be creating its own software based CPU bottleneck on a lot of systems (probably a hangover from being developed for consoles).
