Looking for a laptop for CAD

[protoserge]

What is your actual budget for this? Are you looking to get one or two computers?

How detailed do you get with your CAD files? How large of an assembly do you typically build?

In your list, you have an Asus N53 with an i7-740M. This is an older processor (2-3 years), but should be just fine.

Any of the systems you posted should easily handle these programs. For reference, my AMD E-450 ran SolidWorks and LabVIEW, and that is just slighly above a dual core Atom.

I picked up a refurbished Lenovo T410 with an i5-520M and NVIDIA NVS-3100 for $340 (+$75 for a new 9-cell battery, was not required) off Newegg last month. It handles SolidWorks much faster and is a great budget buy.
