So I went back through my order history on the last PC built last year to compare prices from then to now...and WOW!
Prices are In Pounds Sterling and what I actually paid are in brackets for the three items that have gone up a lot:
x3 8TB M2 drives: £540 each (now priced at £1099 each)
128GB DDR5 RAM: £466 (now priced at £1464)
Nvidia 5090 GPU: £2220 (now priced at £3299)
Had I waited 8 months until today, It would have cost £3754 extra just on these three components!
On the plus side, If Apple manage to bring a decent M5 Studio Ultra out (soon) that can actually compete with really heavy GPU stuff like Nvidia does, I'll be quids in by selling one of the x2 identical PC I have now to fund the Studio as even second hand prices seem really strong.
That sounds like a real beast of a system you built.
