You didn't offend. I made the purchase because I need(ed) the compute resources to run and test clusters.
The reason I have a shit GPU is because these CPUs aren't built with one. That is how I know you don't have experience.
Everything I run has a web console so why waste money on a expensive GPU?
I ran the equivalence of 1/2 the compute on AWS for < 14 days and paid over $1k so yeah, my purchase was not totally in vain.
You would'nt buy my computer for it's current state - if for gaming. You'd buy it for the CPU, memory, maybe the NVME drives; all you'd need is a GPU. People like the OP want someone to build one for them, whilst others like a blank canvas and this is what this is.
I have collected many spares over the years and I'm over having the latest and greatest, plus I can do with a lot less powered spares.
