<p>Hi,<br>
</p>
<p>I would also recommend going with the 15 inch display. The 13
inch display is on the lower side and probably not a lot of fun.
QGIS has several dialogs and also the styling side panel
introduced in 2.16 needs a bit of a minimum size. If your display
is only 13 inch you end up scrolling a lot in the dialogs and
panels.<br>
</p>
<p>(Q)GIS needs a bit of a screen size to use it efficiently. Of
course, if you are not on the road you can also connect an
external display, which I also recommend.</p>
<p>I would also upgrade RAM a bit. As others said, the GPU
acceleration is not yet supported.</p>

<div>Hi,</div>

<div>Currently GPU acceleration is not used. Maybe some plugins
can use it but I have not seen anything yet. I have put in a
request to use GPU for the qgis 3.0 raster calculator as it
needs to be upgraded for huge rasters. Currently , the qgis
raster calculator can not handle big rasters. The new version
needs to break up the raster into smaller chucks and if you have
done that, you might as well use the multi CPU ou GPU to do the
rest. I an hopping this will be fixed for 3.0. Rendering is
multithreaded and will be faster the more cores you have.
Personally, I would go for the quad core without even thinking
for this and other softwares. I would think of getting an ssd
also. I have not used qgis on a MAC (PC and ubuntu only) but I
expect this comment to be valid for Macs also.</div>

Yes, and it is expected that it will make even more use of
multiple
<br>
cores in the upcoming QGIS 3.0 version.
