Been too busy working to keep up with computer specs...

I need to build a workstation to run Solidworks 2007on. Should I get a  Dual-Core Xeon; (2x) Dual-Core XeonsaQuad-Core Xeon, or (2x) Quad-Core Xeons?

I've got some large assemblies which are going to getsignificantlylarger in the very near future...I'm checking thestats right now,but this is going to take a while!

I figure I'll get the go ahead for about a 4k budget (alreadygot adecent video card) so that should allow me to spec outtheworkstation as I see fit.
