as another CSGO player, I am seriously considering one of the high end ryzen 3000 cpus. if the performance is as advertised, it looks like amd will be the single thread king for at least 6 months.
Before you pull the trigger wait to see what the latency between the chiplets/memory does to framerates. We'll know once benchmarks are out, but remember not just to look at average framerate but minimums too, you can have high framerate with terrible stuttering.
