Well, SSD drives in general are the best investment you can make to speed up any modern computer. They truly make a LOT of difference in terms of speed for booting your computer, loading files, seeking files, etc. But the cost-performance ratio is quite high and you are paying MUCH more for those increases compared with the value of size a mass storage HD is now.

It will not help Vue at all in terms of making it render faster or perform better in general. What is a good investment is a true 64 bit OS like Snow Leopard or Windows 7 and lots of RAM. Also a very good graphics card helps along with a modern CPU with multi-cores. Also, setting up a render farm if you are serious about speed and doing a lot of high quality renders will help too.
