I think you will find something usefull, just start saving some money ;-)
look for certificated drivers for the grafics.

Greetings

you need cores, ram and a professional gpu like an nvidia quadro or ati fire.
A core i7 with 8 gb of ram and a gpu from the ones mentioned above will do fine.

I would advise you to invest more money to a powerfull CPU... i have 8gb of ram and never seen it over 50%.. My cpu is an intel i7 2630QM 2.9ghz and when i do a flow simulation, i can hear some noise and the clock is stuck at 100%...

1. Get a powerfull CPU
2. Get a powerfull GPU (as Manolis mentioned above)
3. With 8gb of ram you should be fine (Except if you want to model an aircraft with every single part on it.. Then you should need a bit more )

Dell Precision M6600

If you are willing to sacrifice RealView Graphics, you do not need powerful graphics capability. A 17" screen is good. You do not need a large amount of memory or hard drive capacity. CPU is most important. A low end laptop is not brilliant but surprisingly, it works OK (if you want so save a lot of money).

Typically if you're going higher end laptop, SolidWorks users will go with the Dell M6600 or HP8760 . If you want something lighter the Dell 4600, HP 8560w, HP8460w.

thanks all. I have spec'd out a Dell M6600 and will probably go with that.
