Parts and Multithreading

My question is rather simple.

I have solidworks 2010 64 bit with a quad-core cpu 2.4ghz.

my parts are complex enough that if i wanted to do a simple extrusion or a hole - it takes 5-10 minutes easy...

i know there is no way around this..

so my question is - will solidworks 2013 be fully using all of my cpu cores to do part rebulds? i know simulation does but i need part rebuild as well...

Thank you!!
