Hi,

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.


(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.

I would also upgrade RAM a bit. As others said, the GPU acceleration is not yet supported.

Hi,

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.

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