    It is a i-9 processor, you should already know what to expect. Good but not insane, hope you enjoy it if you get it and please make sure that your motherboard is compatible with the product before you get both

    Really great for gaming even in 2021. My chip runs pretty hot though. If overclocked mine still reaches 90c under stress tests with a 240mm arctic AIO. That's the silicon lottery for you, YMMV.
