    I've always been an intel fanboy, but when I saw the specs on this processor I was sold. I do a lot of video editing and motion graphics and this thing gets the work done fast.

    Amazing processor for gaming, video editing, rendering, multi-tasking, and really just about anything else! It's able to handle pretty much anything an average person will throw at it. And it's future proof with it's extra cores and fast clock speed!

    Absolute workhorse. Unless you're like heavy into gaming.. don't bother looking at the 9900k or the KS. Team Red!

    After 10 years on a quad core the 12 core 3900X was a leap into the future, I can keep as many browser tabs and applications I want open all day long with no slowdowns. Imagine having three times the power!

    AMD is giving intel a run for their money. excellent for gaming and giving the price they include a solid cooler which looks great and gets the job done. if you are planing on overclocking it then i will def recommend upgrading the wraith prism

    Best dollar to performance CPU out there. You’re getting ridiculous amount of processing power, at a better cost then the competition at this price range. 10/10 would recommend.

    This thing is absolutely amazing. I upgraded from the 2700X to the 3900X and I am never looking back. Customer service kinda sucked and the shipping got delayed, so I probably won’t be buying anything from BestBuy.com for a long time, but this product is awesome

    Too expensive for how quickly it gets outdated and smoked by later versions. You'll buy one and within 3 months AMD announces a new line and your current CPU already lost 100-150 dollars in value. BUT - it's a fantastic processor

    Pretty good bang for the buck. It worked with my build for my pc pretty good. Also came with Borderland 3, The Outer Worlds and 3 months of Xbox pc pass. Extremely happy with my Ryzen 3900x

    After a lot of research I decided to switch from intel to AMD and boy I'm glad I made the switch. Great processor for work and play. Plenty of cores to satisfy the most core hungry program. Great overall performance I could be more pleased.

    This thing is a Beast. Runs everything so far that I have thrown at it. Just a warning the Ryzan 9 does run hotter then normal. I hooked up a water cooling system and now runs at full load under 68 degrees

    I know you want it.. Besides shipping issues on my end, this card is great. 12 cores and 24 threads. Better then the specs of the new PS5 and XBX Series. Cant beat it.

    Ryzen cpu's have been very good to me. This cpu is fast and with a little boost does what I need it to do. I work with very large picture galleries and this has zipped through them at a very fast pace.
