    Pricey but if you want top of the line intel in 2020, this was the chip to chase. Packaged in a ridiculous plastic "thing" but otherwise quality intel multi-core that really cranks.

    I got a pretty badly binned 9900k, couldn’t even get it stable at 200mhz overclock. That being said every chip is different and overall the 9900k at stock frequencies still has been a great upgrade from my 6600K

    Purchased this discounted on Black Friday deals. Immediately OC’d it to 5.1ghz. Very stable OC with a 5236 Cinebench R20 score with temperatures peaking at 80° But hovering around 77° average. Handles everything I throw at it with ease. Runs in the 50s and 60s when gaming on Modern Warfare with all settings maxed. Very happy with silicone quality and the performance of this chip.

    Processor certainly gives you a good speed. But I’m not really seeing it outperform my old processor, a core i7, 8800K, that much. Perhaps I’m just not using the processor to my potential. An upgrade nonetheless.
