I put an SSD drive into my laptop about 2 months ago.
I had Vista 32bit before on a HDD. It was slow, When the system started it took more than 2 minutes for the system to load everything.
Now I have Win7 64bit which boots from the SSD drive.
It is really fast, the whole system is up and running in about 35 seconds.
Your whole system will be faster and more responsive thanks to the SSD drive.
But I agree with Matthew, ArchiCAD specifically will not get a great boost in 3D from it. The whole system will benefit in general.
