Playing games on workstation is plainly stupid. Period. A consumer CPU will do a better job for way less money.
But, to be fair, the storagereview review is not even comparing Xeon to the competition (the Threadrippers) and Level1techs speaks about a Xeon advantage because "It's overclockable" (Threadripper are too, btw)? Sorry to say but If you buy a WORKstation it's very unlikely you'll overclock it, nor you will run it with the case open with additional fan just laying on the CPU cooler. Moreover, I was not able to find the details of the Threadripper platform. It was done on a TRX50 or WRX90 mainboard (the Bandwidth changes a lot)?
That, and the Xeon being faster practically only on AI workloads but not pointing out that those loads are probably, in most cases, better served with a GPU. So IMO these reviews are kinda "Meh" and missing too many points to be considered exhaustive.
