    Before I built my gaming PC I did a lot of research. It was recommended to buy this CPU instead of the 10th gen. I made a great choice.

    Very powerful processor, it barely ever scratches 40% utilization! It’s a great jump from my 6600k that I had before this. Paired perfectly with my 2080ti

    When gaming and streaming at the same time, my old processor was capping out. When doing the same with this processor, I’m looking at 50-60% usage tops. Definitely loving it so far. Was scared to break the box that it comes in, but it is fancy.
