From my co-workers/boss:

We’re looking at getting a Vostro 3700 with an i5-520M 2.4GHz/3MB processor and GT 330M 1GB graphics card.  Will this type of set up be expected to work for SolidWorks 2011?  As a point of reference, we currently run (reasonably well) the 2010 version on a Vostro 1710 with a T5670 Duo 1.8GHz/3GB RAM processor and 8600M GS graphics card.  We don’t intend to use PhotoWorks on this computer.
