You don't need CPUSETS for this small a system.
But setting it is harmless - for example at least one major commercial distribution enables CPUSETS on almost all their product, most of which is running on PC's less powerful than yours.
CPUSETS provides a facility for managing the memory and processor placement of jobs running on what are typically big NUMA systems. Job X runs on CPUs 0-3 with memory on Nodes 0-1, while Job Y runs on CPUs 4-7 and Nodes 2-3. And bigger ... to hundreds and thousands of CPUs and Nodes.
