Well yeah, I also absolutely agree with the thrust of what you're saying here, but I think where we differ is that for me, the specific machine the OP is looking at is different from the entry level model going for about $1,699 - it's clearly overkill for a general use computer, and at this point I have to question, if you want a performance-oriented machine if the 2015 still cuts it today, considering you can get a brand new computer with 8th/9th gen chips, latest graphics, DDR4 RAM etc etc for that sort of price. Absolutely the 2015 is still a competent computer for even moderate tasks, but it is now undeniably ageing internally and I think that deserves to be a point of consideration here, as it's only getting further behind over the next 2-3-4 years. Already a 4th gen 22nm quad core CPU scoring 4391/13926 in geekbench vs an 8th gen 14nm hexacore scoring 4615/18471 is beginning to add up to a significant difference in CPU power. But more significantly, on the GPU side, even the most basic 555X in the 2018 is around 1/3 faster than the GPU in the 2015, with 2x the VRAM, and this is let alone what's in the iMac or a Windows equivalent laptop. Now, as OP has opted for a machine with the graphics card, I'm guessing he's probably going to make use of it. I can't say for certain unless he comes back and says specifically what he plans to do, but that's how I'm interpreting this choice of machine.
