FYI 8600K 6 Cores, 6 Threads vs. 9900K 8 Cores, 16 Threads DOES make a difference

Asrock Extreme Z370 - cheap - last generation model 1151 socket / I upgraded for the same socket & 64GB 3200 (& 12 harddisks/SSD), 9900K is on sale cheap on local Amazon netherlands 333€ (dropping still, now 300€) and these latest batches are faster at 5GHz turbo
