GOT A NEW COMPUTER BUT NOT NEW PERFORMANCE

So I just got a new computer that is so hot, it can cook a chicken.

http://www.amazon.com/Lenovo-4351E1U-Thinkstation-E5-1650-6-core/dp/B00FE2LEIG/ref=sr_1_1?ie=UTF8&qid=1440772396&sr=8-1&keywords=lenovo+4351

Changes to that system are... I have 32 gig of ram ( Soon to go to 64 ) and a A 250 gig solid state hard drive running Windows 7 pro.

6 corers and 12 separate threads!

I am using 12% of the CPU and almost 100% of the ram for an assembly.

Why is Creo not using all my CPU availability?
