    It’s overkill in every sense of the word for how it’s being used. It is currently killing it at stock voltages.

    My first experience with an AMD processor. It's served me well. 12 cores isn't exactly top of the range anymore but it was when I bought it. Surprised it's still screaming along. Comes with overclocking capability with the touch of a button or more advanced options if you are so inclined. I'll ride this processor until it is dead and it seems to have plenty of life in it after more than 2 years running.

    Powerhouse.

    Get one used and you will have a Price/Performance monster.

    Might be the greatest CPU ever made... honestly... incredibly powerful, fast, and super reliable. Never have had a single problem with this chip... only thing is that it runs a tad hot when under moderate load, expected for the output that this thing does tho. WOULD RECOMMEND!

    Oldie but goodie. Massive upgrade from the 3600 I had previously. 12 great cores for sweet sweet parallel compute, and I got it super cheap since it was used.

    Amazing CPU for people looking to build a video editing focused build.

    Adequate and still relevant today. It is a genuine workhorse. If you can find it at a decent price, definitely grab it.
