Solidworks 2011 Hardware Upgrade Core i7 2600k / Quadro 2000

Hi All,

I've just built up a machine for my client to use solidworks on and its not quite fast enough for them to render on.  I'm not overly familar with the program so I was hoping someone could please tell me what i can upgrade to speed up the rendering times.  Here are the current specs:

Intel i7-2600K 3.4Ghz

ASUS H61 MB

8gb Memory

Leadtek nVidia Quadro 2000 1gb

Intel SSD 120GB

Thank you in advance.
