[gmx-users] about quality of CPUs with GPUS

By quality are you referring to performance? The ideal CPU-GPU balance
depends on the type of runs (system, settings, FF) too. However, in most
cases, for current GROMACS versions you will need many and fast cores to
balance with the 1080 Ti -- which is about the fastest gaming GPU out there.
What kind of simulations do you intend to run? Have you considered single
socket workstations systems instead of dual-socket Xeons?
