Ultrabook for AutoCAD LT 2014

[john-galt]

I am looking at buying an Ultrabook for light use (20Mb files) / schematic design using AutoCAD LT 2014 whilst out and about.

I would also like to be able to run  / view / ammend small (<50Mb) Revit models, along with Excel Calc sheets, structural analysis software (BeamPal & Strand7) & SketchUp Pro. No gaming.

I wont be doing any rendering etc....

All heavy work will be done on my office T3610 desktop or M6800 'laptop'.

The questions are:

1. Can HD4400 / HD5000 run AutoCAD LT.....productively?

2. i5 or i7?

3. Anyone had / share experience of running AutoCAD LT on this sort of setup?

I am looking at:

Lenovo X1 Carbon i7 4550u or i7 4660u / 8GB Ram / HD5000  

Lenovo T440s i7 4600u / 8 to 12GB Ram / Nvidia GT730m

Any advice would be much appreciated.

i5 or i7 rated at close to 3GHZ Speed or higher is best.
8G ram minimum.
SSD harddrive ideal: 256G in size is minimum, 512G ideal (you'll run out of space on a 128G sooner than you think).

If REVIT is happy with the video card, then LT may be fine with it too: check with your REVIT peers in that forum.
