Comment on Ram Disk Creator

It'll speed up any program that reads and writes from a certain location often, as long as that location is on the ram disk. Handy if you're dealing with large files, because it can (effectively) read and write instantaneously, instead of being limited by your HDD speed.
Programs also tend to start faster. I've noticed game launches and map loads dropping to less than half in some cases (depends a lot on the game, and where it stores its data).

Oh, if you have a lot of RAM, this'll help make video encoding faster, as that involves a lot of HDD reads for the original file. Even faster if you have room to save the final file to the ram disk.
Videos will also play faster, so if you notice periodic skipping at about the same time as when it reads from your HDD, try putting the video into the ram disk. If the reading operation is pushing your computer past what it can handle for the video, it'll speed that up.
