I have two computers in the shack- a 2006 Core Duo running XP with 512 Mb RAM,
passmark score of 1,100 and a high end workstation running Windows 10 running
on 4 Xeon 2690 CPUs, 32 Gb RAM, SSD, with a passmark score of 25,000.
There is zero perceived difference while running N1MM+ with one MMTTY decoder,
two 2Tone decoders, and one GRITTY for diversity decoding.
In addition to the logger, I run VE7CC client and microHam router.
The NUC will do just fine. I have a NUC clone as well and its passmark is 1500.
You don’t need much CPU to run the logger and 4 decoders.
