Retailer reviews (amazon, newegg, etc. ) aren't always a direct indicator of the communties opinion as some people only post a review when there's a problem, which makes it a unreliable indicator of the performance of the majority of components. To counter this, I'd look at a few professional reviews form youtube, tom's hardware anandtech, but not LTT, or more specifically, the forums.

Other than that, I'm relatively active on the official PCPP Discord,
