I am jumping into the world of solidworks. My laptop just died and i want to replace it with something i can teach myself solidworks and inventor. I am on a tight budget and do not plan on working on assemblies more with more than 20 parts. The two video cards i am looking are are:

512MB ATI Mobility Radeon(TM) HD 5470 switchable graphics [HDMI, VGA]
1GB ATI Mobility Radeon(TM) HD 5650 switchable graphics [HDMI, VGA]

Thanks for the advice.

Steve
