Hi(gh)!
With an ageing AMD FX-6200 hexa-core crashing every few hours, I'm
contemplating a major hardware upgrade! Possibly, the crashes result
just from a power supply too weak (450 watts) for my recently installed
new graphics adapter (Nvidia Geforce GTX 1050 Ti), then the issue could
be fixed for less than 100 euros. If mainboard and/or CPU are wrecked,
it might be somewhat more expensive (an AM3+ socket mainboard plus a
slightly faster hexacore CPU - an AMD FX-6350 clocking at 3.9 GHz would
be about 180 euros, with the flawlessly working DDR4-1333 RAM bars still
being usable). However, as my loved one is ready to spend even more
money for my computer upgrade, I really would like to how to get the
highest POV-Ray performance per euro and/or per watt of power
consumption... are there any reliable benchmark lists for current CPUs?
I've seen those Intel 2600s socket board capable of managing up to 128
GiB of RAM (which would give Khyberspace and POVEarth a serious
boost!)...and matching 18-core high end CPUs (which probably would be
too expensive even for Micha), and running such a beast would really be
tempting... but how fast are they really?
See you in Khyberspace!

A 450w PSU looks like a little weak for a modern computer. If the PSU is
under rated, it's currents and voltages become erratic, leading to
crashes. Try something in the 600-750w range.
A rule of thumb is that the PSU should be rated to about twice the
actual power consumption of the computer for optimum effecienci and
stability.
If you go the way of a totally new computer, then, for POV-Ray, you have
those considerations :
Video card : NOT important at all -> Take some entry level offering.
CPU : It does all the work. Aim high ! Larger instructions cache is a plus.
RAM : As much as you can afford. If possible, choose the lowest latency
that you can find. Long burst length is normally not a factor as most
access if for relatively small, randomly located, data chunks.
Drives : SSDs will make you save on the electric bil side, but cost
more. HDs are beter to store huge amounts of data that don't need to be
accessed very quickly, like most media files, but they consume more
electricity.
Monitor : Need a good quality one.
PSU : Need to be over rated to ensure stability.
Don't forget a good cooling.

From my own limited experience-- with a crashed WinXP computer last year-- I
would suspect the power supply as being the cause. Which might then damage the
motherboard, if the PS really screws up. In my case, the motherboard got fried
when the PS failed catastrophically. (A cheap OEM power supply, no doubt.)
I'm no expert with this stuff, though.
