Pretty incredible for the money.

Pros: -Boosts up to 3.8ghz on all cores ( I synced all cores in the Asus BIOS )
-Runs games flawlessly ( EVERY single game that I've ran has had a minimum of 70-80fps on ultra graphics at 1080p, I paired it with a GTX 1060 6gb )
-With a Deepcool Gammaxx GT TUF Gaming Alliance Edition cooler my max temps have never exceeded 58c-60c while under 100% load
-Integrated graphics for trouble shooting

Cons: -The price is... well... pricey in CAD

Other Thoughts: Absolutely fantastic CPU. I've played SC2, BF1, GTA V, WoW, Rainbow Six Siege, Assassins Creed Odyssey, Shadow of the Tomb Raider, etc... and they ALL run incredibly well with this CPU. Here's my specs:

EVGA 1060 6gb
ASUS ROG STRIX B360-G GAMING
Team T-Force Delta RGB 8GB ( I have another 8gb coming )
DEEPCOOL GAMMAXX GT TGA TUF Gaming Alliance Edition
EVGA 500w BR
Intel 545s 512GB
Cooler Master MasterBox MB500 TUF Gaming Alliance Edition

Laggy for a seemingly high end CPU, not the best bang for your buck

Pros: - 6 cores, at the least it can play high end games moderately well, not all of the time though.

Cons: - Struggles with loading up games, many bouts of lag experienced.
- No overclock method. Certainly wouldn't complain if there was a K version but there sure isn't, thus you are stuck at the 2.8 GHz with only the involuntary turbo or other very tedious methods of figuring out how to speed it up.
- Overtly expensive when compared to better CPUs. The i5-8600K costs only 30 more dollars yet has a significantly higher GHz and is overclockable if even that isn't enough. This CPU isn't the best bang for your buck.

Other Thoughts: - Overall if you are looking at this review before buying this I strongly recommend you buy a better and only slightly more costly CPU such as the i5-8600K. The 8400 can game, but not nearly as well and for about the same price in PC terms. I will likely be replacing my 8400 with a better CPU.
