Excellent product 7/15/2020 12:43:52 PM

Pros: This processor has handled everything I've thrown at it.

Cons: The default cooler does not use the guides in the motherboard so make sure you line it up properly to the back plate

Overall Review: Overall it's a great processor for its cost and will be good for a couple years to go

Awesome Starter CPU! 7/15/2020 9:53:38 AM

Pros: This CPU has done me very well, it pairs nicely with my RTX 2060 Super, and is overall a good CPU. Obviously there are better options on the market, but for a higher cost. This CPU is a great bang for your buck purchase.

Cons: I’m not 100% sure if my CPU is causing the occasional window lagging and just lagging in general. It doesn’t happen often so it’s not too annoying but it happens occasionally. I have 16 GB DDR4 3200 RAM, RTX 2060 Super, Asus x570 prime pro mobo, 1 TB Seagate HDD, and of course, this CPU. I would make this review a 5 if the problem is that I don’t have a NVMe SSD, I’ll figure out if that’s the problem when I get my SSD soon.

Overall Review: A very good processor, especially for people just starting out, such as myself. It’s a good, budget CPU to get you understanding your computer and how it works. From there you can move onto a better Ryzen processor, but this will do you just fine.

A nice upgrade, can't beat the price 7/15/2020 9:40:16 AM

Pros: Great first AMD cpu; performing right at the top of most bench marks but for ~40% less.

Cons: I'm sure there is a way to do it, but I can't get my chip to boost past 4.05ghz. Was expecting out of the box boosting to the advertised 4.4, which is disappointing. Still performing great though, and I imagine running cooler + lower power because it's not hitting that theoretical max.

Overall Review: So far, I would definitely recommend the 3700x. It's a good value, has good power and the included cooler was surprisingly good (comparing to stock intel from a few years ago).

Pros: Fast and reliable

Cons: none

Overall Review: A really amazing upgrade from a huge cpu bottleneck, my cpu used to sit at 100% but now it doesn't come close to that. I am really glad about this investment. I would recommended.
