$1,300-1,800 faster for 24%? Is that really worth it? the delta between 24% and 33% is even smaller (for a smaller $ gap but not too much smaller). The 33% isn't necessarily wall clock time for the whole workload. Some of those are spikes in very specific tasks (the standard deviation on the changes is pretty substantial) . Whether it works out depends on hourly billable rate. It there is a ton of time where can't do anything but stare at screen and wait then ths is savings. If can time slice task then it is an a subset.
For my first ever RAM expansion of 8 KB (yes KB, not MB and not GB) I paid 400 in 1981 in Europe. Was this worth it? Commodore 64, Amiga systems. Was it worth it?
No, it never calculated by the actual money I made at that moment. But it added to the fun factor and to the knowledge I gained in newer technology which has helped throughout my career.
24% is in relation 6 to 8 core. I would assume to be 50+% in relation to 4 core. Internal redesign, with better thermal, more reliable components, T2 chip, more external ports, ECC RAM, better GPU ... is it worth it?
At the end and important to me is the fun factor and together with the above this makes it worth it for me. Every one has to make their own decision and as it had been discussed and I admit this might not always be rational.
That is just temporary and iMac isn't only option if budgeting out to $4,999+ price range .
Really? If I am done for now with Windows, need a new system, don't want to install and build up my own system as in the past. If I just want a system to work, which 6 core system do you recommend now? The outdated Mac Pro or wait until 2019 Mac Pro or an iMac with 6 cores in 6 to 12 months?
It seems that I am not seeing the same thing you are seeing.
Currently I see a 4 core iMac that agreeable potentially can do the job, but on the end of its life cycle, a Mac Pro past due and iMac Pro with current technology which adds as I mentioned to the fun factor.
For me this was an easy decision which gives me with "pro" components a worry free system probably lasting for 6 to 7 years (with Apply Care a minimum of 3 years).
