I misunderstood. You are meaning RAM to load the SolidWorks program.
I thought a Gigabyte of RAM was only a couple hundred bucks at most. Is it not the same in Italy? Last comments I've seen on this Usenet group have noted 2-4 Gigs of RAM suit most projects, and only the largest projects need to go up from there (with newer hardware).
Ultimately, the project needs the right tools, and the project price has to pay for the tools.
I understand the overall cost issues, and I don't like paying "a lot", but I do remember the days when 3D CAD was anywhere from $30,000 to $100,000 per seat and ran on workstations that started at $30,000 per box.
