If your 2016 MacBook is fast enough for everything else besides gaming, IMO a gaming PC + MB is the best option. Using the best tools for the job.
Agree completely. I still vastly prefer my Mac for doing work, but the Cook era Apple is the antithesis to being an enabler of Mac gaming that the previous decade was. PC for play (and very CPU and GPU intensive work, hence the beefy CPU and workstation GPU rather than a gaming one), Mac for 90% of other work, productivity tasks, and just general use works out extremely well for me. I've got my PC workstation/gaming dual-use set up, and two workstations with Thunderbolt displays set up for my Mac and I just plug my MacBook Pro into whichever one I'm going to be using at that time and go.
