I'm working with an unholy large assembly, and  was hoping I could get some advice.  My companies core product has about 300 parts in each unit (counting things like the O-rings and fasteners), and many of the parts are pretty complicated in themselves.  There's nothing bad working with the unit assemblies, but when I try to add 840 of them to the full system they operate in I pretty much nuke my computer.  I just got a new workstation with an i7 860 CPU and 16GB of memory, so I don't think I'm too resource limited unless it's in the rendering department.  Can anyone think of a way I can get the units added to the system to check for all of the fitment issues without killing solidworks?  Thanks in advance for the ideas.
