I had a fire at one of the usb headers on a 12 yo old asus m2n-sli deluxe 
mobo last fall, replaced it and its 2.1GHz phenom with a much later asus 
X370 carrying a 6 core 3.7GHz i5 and 32Gigs of dram. Old board was from 
before UEFI days.  Maxed out at 8Gb of dram.

I am still booting from the same hd, same debian stretch install, no 
re-install, on the new board.  Even the video self adjusted. Which is 
only a data point. So I'd have to say its dependent on the mobo maker.  
I am partial to whatever works, and for 13years now, asus has just 
worked.

Interesting detail, that 3.7 GHz 6 core? If I ask gkrellm to show the 
clock speed of the individual core, its usually running at 800MHz unless 
really busy.  Bought biggest heat sink/radiator for it, too tall to 
allow case side to be reinstalled, but I have yet to detect an actual 
temp rise, and gkrellm is showing all 6 cores running at 29C.  I am 
amazed. Quicker than stink compared to the old 125 watt phenom, yet no 
heat.
