Use of an SSD?

I run COMSOL on a core i7 with 32GB.

Occasionally I run out of memory, and things get VERY slow.
Now more RAM is clearly best.

But how much benefit would there be in installing an SSD and using it for the Windows page file?
One of the very fast read/write variety.

Would it be worth installing COMSOL itself on the SSD as well as this Windows page file?

I realise there is a life issue with SSDs, but it would have nothing on it that can't be easily replaced; all that goes on the conventional HD.
