Solidworks Sudent 2011 on GTX 470

Hello !

my teacher give me the key for the SDK student version 2011.

my problem is :

when i create big assembly, or big model ( like a fractal cube... useless but interesting. ) my PC lags. and sometimes Solidworks freezes for 10 minutes.

i notice that my GTX 470 stay at 1% of utilization : it means that my graphic card is no used by Solidworks.

so, Can i use it legally to make solidworks go faster ? ( gtx 470 is a consummer version )

or is it reserved for professional graphic card like Quadro FX ???

thank you

( sorry for my English, but i'm French ^^ )
