Why would it be important to put the data on an SSD?
I have an 120 GB SSD to boot my system and store all my programs, including CS6. I have lots of software loaded and my 120 GB SSD is only 3/4 full. When I bought my SSD about a year ago, bigger SSD's were substantially more expensive. My intention from the beginning was to only use the SSD for my system and programs.
My processor is an Intel i7-3770, which I think is still pretty fast by today's standards. I have 16GB of RAM. I felt that 16 was balanced for the system and that more would add unnecessarily to the expense.
I keep all my data on two 2TB hard drives with enough free space for optimal speed.
I too would like to speed up my workflow, but it certainly has nothing to do with my computer.
I don't think moving my image data onto my SSD for editing would make any difference. Not for photography. I can't think of any function in photoshop that is not instantaneous.
For designing your system, I find this website to be very helpful.

There are lots of other benchmark comparisons if you look around at the tabs, etc.
