running your OS on a SSD

[lukeforrest]

I am building a new computer and thinking about buying a SSD (64 - 120 GB)
The reason for wanting to buy one is I have been told that running your OS and puting your program files on the SSD will make the computer faster becuase they will open quicker

Making boot up time and program open a lot faster

Is this true and if you have an OS or program files on SSD what was the speed differnce you had when they where on a HDD

So on the SSD should I only put programs that start on boot up like messanger and utorrent but not stuff that I have to click on my self to open like winamp and Firefox ?
