People still benchmark CS:GO because it is one of the few games that is CPU bound that still actively being played today. It's one of the few games where a single core performance and memory latency has a big impact on overall performance.

Intel always had a huge lead on CS:GO until Zen 2 where the gap finally closes up, which is why a lot of people is referring to CS:GO benchmark when talking about Zen 2 in context of gaming.

actually a lot of pro players are streamers, so they at least need a good cpu for game+stream. some even have a setup with two computers. actually streaming games (especially new ones) still needs at least the i7's.
