Engineering Pc

So I just graduated college in electrical engineering and landed a job at a company that builds agricultural equipment. I can design a circuit but as far as computers I just don't have current market knowledge to know what would be best. Because I work Primarily in systems involving mechanical and electrical design, I tend to run solidworks,autocad, autocad inventor, cadence capture and autocad electrical along with the random simulation software.  

Price-"$1500-2500" would like to keep it down but willing to spend for a good reason. 

currancy is $US

Big debate is running an I7 or going xeon.

As far as storage goes i was thinking just one ssd because it will run off of a server anyway so no need for a HD.

well i was thinking about a few things.  but i realy need to know how  cpu heavy the simulation software realy is. if this  software is very thread demandig, i was thinking of getting an socket 2011 ivy-bridge -E setup. with maybe a 6 cores 12 threads if the simulation software is realy heavy.

If it meets the requirements to run autocad inventor pro 2014 it should run all the simulation software, we use the autodesk simulation suite.

i did some research about autocad inventor, and i found out that a GPU is realy important, i saw some benchmarks on which showd me that the nvidia GTX680 was leading the table. on the 2013 version of this software. so i was thinking that a GTX780 as a gpu would be your best bet.

i come up with 2 options, on which i think this will fit your needs.

option 1 with intel i7-4930K: http://pcpartpicker.com/p/25k4i

option 2 with intel i7-4820K: http://pcpartpicker.com/p/25k2N

Hasswell option: http://pcpartpicker.com/p/25kd9

Offcourse on the Hasswell build you could cheap out on motherboard if you like. This are just a few builds to give you some inspiration ☺

Ok thanks for the ideas.
