Workstation Improvement to run Scan to 3 D surface wizard faster(mesh to surface conversion)

Guys

Im running Solidworks Premium 2011 SP01. Im using Scan to 3D add-in to convert point cloud data (with more than 200K points per file) into mesh and then to surface.

The problem that I face here is that the time consumption is too long especially when converting mesh to surface. It takes more than 6 minutes.

Im running Solidwork on my machine; Dell Precision T3500 intel Xeon quadcore / 6GB RAM / Nvidia Quadro 600 / Window 7 Professional.

Can anyone advise me on what aspect should I improve/upgrade my workstation to speed up the conversion process?

Thanks in advance.
