i´d like a cpu-frequency fullout. therefor a cheap pentium 4 can be as strong as an 10900k. lots of LN2-fun for small money
maybe best 5 in different nm, so you can´t only use skylakes like 6700k, 7700k, 8700k, 9700 and 10700k, but have to use for exsample a 14nm cpu, 32 nm cpu, a 45 nm cpu, a 65 nm cpu...?
