Exceptional for everyday workload
Having used the Intel Ultra 7 265K for around a few months now in my current build, it has been nothing but perfect when it comes to me doing resource-demanding tasks such as music production, the occasional video editing and even for gaming. The CPU's 20 cores allows you to handle any kind of workload with ease and I would personally definitely say this is a very high-tier choice when it comes to picking parts for a beast of a computer.
