Most games only have noticeable hard drive access during actual loading screens. Such as when you zone into an instance in World of Warcraft. A progress bar comes up on a loading screen. The only part of games that you will notice go faster is that loading screen.
Photoshop I don't think does much hard drive access either. Only when loading on startup, saving, and opening files.
games will get higher frames per second from faster hard drives. The way they are designed is to be RAM intensive, so that you don't need a fast hard drive.
In all honesty, I can't think of any programs that would benefit noticeably from faster hard drives either. I'm sure there are some, but they are rare.
The paging file is a section of your hard drive that Windows uses for virtual memory, to reduce stress on your actual memory. Since it is on the hard drive, it is much slower than actual memory, and it is recommended to disable the paging file if you have more than 2GB of RAM.
