The Precision M6500 is the system to buy.

That looks amazing but I doubt I can afford that :(

That is what you'll need to run that package well.  Anything less will hamstring it.

If you can't afford a notebook of that caliber, buy a desktop - it'll cost 50% less and handle it well.

I need the mobility. 

Decide where you want to compromise, then.  You're not going to get stellar performance from those applications on anything other than a high-end Precision - so, if you're wiling to take low performance, a mid-range notebook will work.  However, finding one with the video chip you're looking for may not be easy - many vendors were very badly burned by nVidia's faulty engineering and have dropped nVidia in many product lines as a result.  Again - it's a matter of compromise.  If you can't afford a full-blown mobile workstation, you may get by with something less - kind of like squeezing a family of five into a Civic rather than going for an Accord.
