Spice is great!

Spice simulators that utilise GPUs have been available for the last 15 years or more. On circuits like this with only a few few nodes they will not offer any advantage. If you're designing ICs with thousands of transistors the simulators from Empyrean (ALPS-GT) and Synopsys (Primetime Continuum) have got the nod of approval from the design community (feedback to Cooley).

At the LTSpice price point there'sa NGSpice based simulator (CUSpice) that can utilise a GPU for some spice models (IIRC caps, resistors, inductors, voltage and current sources and one or more of the Mosfet models).

My computer at home died but luckily we had an identical oldish box at work and the RAID drives moved and worked in the old box.

One of these years I'll need three new Win10 boxes, and maybe a spare, with all the tools and junk installed. I'm not looking forward to that. Win10 is terrible and 11 is probably worse.

More RAM and more compute power would be nice.

win10/11 is fine, and they can run linux too much easier when deveping for e.g. rpi or Zyng

single core performance haven't improved much for years

They are E5 1603 quad core 2.8 GHz. 8G ram isn't enough, considering that Firefox alone can run maybe 20 processes.

Maybe the sim will run faster if I close Firefox.

I use to run the ECA circuit simulator on an 8088 at a couple of MHz!

something like an i9-13900K is more than 2x single , 12x multi performance

High school trig was great, they manage to stretch sin^2(x) + cos^2(x) =

1 into a full semester of material.
