Once my graphics card arrive, then I can do full blown memory testing. It's nice to be able to boot up and test the build with 1GB of memory!

SuperFetch is one of the things that makes Win7 feel fast. Superfetch learns which apps you use over time, then the OS proactively caches them in RAM. This prevents/minimizes hard faults when you access your frequently used applications. It just does it better than it did in Vista.
If you don't believe me, just try turning it off and see what happens :-)
Win7 in general also makes much better use of RAM - you will see more RAM in use for caching purposes - which is a good thing. The more memory that's on the modified or standby lists, the less the system hard faults to the hard drive, which is slow as dirt.
