I agree with Angelo that using Jesus' auto program to tweak your config, using the link you provided, will probably do more harm than good. There is simply a lot more information available about how FSX works now than when that program was put together, and a number of the tweaks it places in your config were suspect even then. In addition, hardware has changed significantly since, and many tweaks simply don't work the same with respect to changing CPU and video architecture.
The links Angelo provides are good, but after years of tweaking myself, I find it best to go with the a largely default config. The really essential tweaks, like the highmem fix, are built into the SE config already. You are likely to get far better results adjusting your video card profile for FSX than tweaking the config. The DX10 guide gives very helpful info om how to go about that process.
