Hi Brian, I really do feel like a rat in a maze when searching for the right computer. I'm quite surprised more people haven't contributed to this post. Either they are lost in the corn maze like me or just can't be bothered to help a pilgrim find his way. After reading your post, last night I looked around on Dell's site and looked at the Precision line, which had a number of choices for machines with GPUs with thousands of CUDA threads and 500 watt power supplies.
I have seven questions and maybe you or someone else can answer them for me.
1) What are the difference among Dell's product lines: Inspiron, Optiplex, Precision, and XPS?
2) What are the differences among Intel's processor lines: i3, i5, i7 and i9 and do they overlap temporally (old i5 is like a new i3, old i7 is like a new i5, old i9 is like a new i7)?
3) What are the differences among NVIDEA's many GPU offerings?
4) Do ArcGIS Pro's geospatial analysis tools only work with NVIDEA CUDAs or can I use a GPU Like Intel Spark or AMD Radeon?
5) Which computer builds are in the sweet spot for multivariable raster and vector spatial analysis?
6) Do all these product offerings provide significantly different experiences and results?
7) Do I really need to be this confused by all these product offers?
I want something which works well, is reliable and will work for 10 years.
