    As of now, the CPU is quite fast. Fastest I've had so far. Can't really give it an honest review because my computer build isn't finished. Still waiting on the new gen of Nvidia Vid cards to drop. So i haven't really been able to put it through any hard work.

    Heads-up: Best Buy is the only place I could find listing this CPU for MSRP and not marking it up into 700-800 territory. As of writing, this is the top-of-the-line CPU for gaming (my primary usage). If you're working on a more limited budget, the 10700k has nearly the same benchmarks for cheaper (and AMD's upcoming Ryzen series looks promising as well). Still, I bought this CPU and haven't looked back. Relatively minimal packaging, easy to install, great performance. Mainly for "enthusiasts", though.

    Good stuff. Runs surprisingly cool (relatively) for its performance. It does consume a lot of power, though, so be prepared for a good quality motherboard and power supply. A lot of headroom for what I do. If you are THE Intel CPU that is available right now that will last you the longest time before you have to do another upgrade, well, you are looking at it. Get it at the right price (sub 460 in early 2021?) and your build will be golden.

    Awesome cpu,it’s stable but runs hotter,I use an asus water cooler,I’m happy Best Buy got some of these in stock,it’s the highest performance intel cpu on the market right now,I won’t build anything but an intel pc after a bad experience with an amd gaming pc,coupled with an asus rog 490 MB the intel i9- 10900k is a perfect combination
