I am really miffed about new machines now.
It's all gone more about energy efficiency in Europe (just like vacuum cleaners that can't suck a pea off a carpet) .
The power of the cpu,s has gone backwards and a lot of them are terribly slow!!!!
I just bought a Dell 15 3000 with AMD Ryzen 5 from Currys while on offer. The processor was much better/more responsive than the new i5's!.
Should easily enough handle some cad parts. I don't really do much in terms of full assemblies.
I am using a refurbed Dell Latitude E5430 (i3 8gb ram) atm and it's a cracking buy for less than £100.
Handles my cad parts quite well and excellent for browsing net etc.
Tbf unless doing major cad files/assemblies, gaming or proper animation work it is all you need.
