Best laptop for arcitecture students

Yep, a Budget would be helpful. If you have the money....oh man you could get a banging laptop for 3d design and architecture
 
3D CAD will need to be a workhorse - I like Dell's Precision M6600. The Quadro graphics card options are great and it supports Desktop-grade processors, multiple hard drives and up to 32GB of RAM. Not inexpensive (especially if you use the RGB monitor), but very high quality
