Hi,

The short answer is no, it won't boost Mathematica's performance for 
most computation.

The longer answer is that the Mathematica kernel doesn't need to access 
the disk a lot (unless you explicitly ask it to write/read things 
to/from disk), and its speed it mainly limited by your CPU.  Where the 
SSD will make a noticeable difference in Mathematica is browsing the 
documentation centre.  Help pages will load faster in my experience. It 
will also significantly speed up the startup of many programs and will 
reduce the boot time of your OS, so it may be a worthwhile upgrade
