You made the right choice, if its only slowing down on loading/saving scenes I wouldn't worry too much just yet :) 

SSD's will continue to fall in price as they did with hard drives, I would wait a bit longer until you can get an SSD at a reasonable price, right now they are at a premium.

I am glad Vue is working better for you now, nothing like more RAM and a faster graphics card to speed up any 3D app :)
