The usability of M3800 with QHD for design softwares - scaling of the UI etc?

Hey There,
Wishing everyone an awesome weekend! I am seriously considering purchasing Dell Precision M3800 with the QHD display with the 3,200 x 1,800 resolution. A lot has been written about the UIs being too small on this laptop. What is your experience? I am need this laptop for the Creative Suite applications and for Autdesk Revit, Autocad, Sketchup, Rhinoceros and other design/graphic software.
I've read people been scaling the whole UI of windows to 125% and running it at lower resolution to get usable graphics. Now, does running this display non-native mean that what see on the screen is going to be too different from the print outs or things I send to others?
Thanks!

 

Pretty sure the latest rev of all the major Creative Cloud applications now support HiDPI. Anything old enough to be Creative Suite (CS6 was the last, right?) will be pretty painful -- Photoshop CS6 and Acrobat X definitely did NOT scale right.
