Which one focuses which way? When I think "workstation", I picture people doing CAD, video editing, and GPU-accelerated simulations and number crunching, in addition to people compiling code.
Games aren't just GPU-bound, either. Unreal says they develop their games on systems with "NVIDIA GeForce GTX 970" and "Six-Core Xeon E5-2643 @ 3.4GHz".
Developing games is different from playing them. The latter takes a pretty beefy GPU (for a given generation) before the CPU is a likely potential bottleneck.
