Looking for a good laptop

[strategos]

Hello, I am looking for a good laptop. I study mechanical engineering and I use programs such as Pro-engineer, Solid Works, Ansys and many other types of CAD programs. I also, sometimes, play few video games. Not too many. I was considering about the Dell Mobile Workstation or the XPS.
If I got a computer with a Nvidia FX quadro, could I play video games? Could the NVIDIA® GeForce® GT, be good for using for CADS programs?

Which one is more important for CADS programs: Memory, processor, video card?

Any suggestion on any type of laptops?

thank you
