SO-CALLED XPS720...

I am Striv and I have a question if anybody would be so kind to provide me some info.  I received my XPS720 and have noticed that my former XPS700 was way faster than this plug.  The XPS720 comes with the nForce 680i SLI motherboard and chipset.

 

QUESTION:  Can anybody tell me how I can determine the chipset in this system?  The motherboard is a Dell Model # 0CK520...

 

Very much appreciated...Thanks!!!
