Intel CPU for ASUS Mining Expert

Hi there, looking to find the most economical way to get a socket 1151 cpu for the ASUS B250 Mining Expert. I have only dealt with AMD over the years and see many options for this chipset, a little confused as I also see Celeron 300 prices way lower. Are these for different chipset boards? Pleas excuse my ignorance, many thanks

They have a list of compatible CPU’s on the ASUS website: . The Celeron 3900 are pretty cheap.

I am currently looking at i3-6100T’s… only I am using the Asrock H110 Pro.
They only use 35W and should save money in the long term.
