I stopped building rigs with celerons. I found the hashrates were too inconsistent and they’re too slow for 8 GPU systems. YMMV. Sometimes I will run two instances of ethminer where 4 cards are mining one coin and 4 cards mine another coin. With a celeron, the system can’t keep up.
I prefer to use i3 7100’s but if costs are a concern, the Pentium G series are fine.
I do plan to add more GPUs to this rig over time so I wanna do it right the first time. I don't mind springing for the i3 7100T as long as there is a legitimate reason too.
is there any coins that 1080ti mine especially well? or is it just raw hashing power in the end?
