New Laptop For 3D CAD/Design Optimization/Dynamic Simulation + Moderate Gaming

I'm looking for suggestions on what to look for in a laptop, or a specific model to be able to take full advantage of Autodesk Inventor and its suite of simulation, FEA and design optimization software as well as a moderate level of gaming. I'm looking to learn right now and buy in the next month or two (roughly $2000 max budget). 

I do a lot of work with a local FIRST Robotics Competition team involving very quick production of CAD models and drawings in a very time sensitive period as well as design simulation and optimization in the off-season. I need something that's not going to lag on me in Inventor during the production of large assemblies during the season and during number crunching FEA sessions in the off-season. I need to know what parts of the laptop hardware to look to for to keep me running smooth and productive. It also needs to be able to travel with me to and from my house and the high school, hence the need for a laptop. 

With the fact that it is a laptop in mind I know it is not going to be a beast at gaming but I would like to keep it in mind for more leisurely times of the year. I do plan on saving up a good chunk of change to build a desktop gaming rig late next year but I would like something now-ish that can carry me for a few years with some mobile power, both for CAD heavy days and gaming heavy days.

 

Thank You. 

specific software? is there some reference pc that you are content with, so we can compare?

what kind of gaming?

Specific software: Autodesk Inventor 2014 (I have access to the new version every year, through FIRST), This one piece of software covers all necessary tasks listed above but there is also the possibility of adding Autodesk Simulation 360 to fill any gaps in Inventor.

 

Games: Modern benchmark worthy games on medium settings and a good frame rate. 

 

The only reference I have is my work computer and the only thing I know about that machine is that it has twice as much ram (16gb) as the other CAD techs and it is the most stable cad machine we have (fewest lags and fewest crashes). 

The more I look into this the more I keep finding on 'workstation class' laptops. I might think about increasing my budget a little and considering one but all of the comparisons and spec information I keep finding sounds like a marketing pitch and not a technical argument for the product. I'd like to find more information on what makes a workstation labtop preferrable to a regular mid/high end laptop but I can't get anything without a sales pitch attached.

 

Does anyone have eny experience in workstation builds/laptops that could inform me of such?
