Pros: I could not ask more of this chip. It is zippy, plays well with Ubuntu LTS as well as modern Windows iterations, games like a champ on default settings with the right RAM (2133 or 2400), DX12 support.

Cons: would love to manually allocate RAM for GPU (this may be enabled on some motherboards but I am not aware); it appears to allocate 1/4 of 1/4 of your total RAM for the video card, meaning it scales by what it finds onboard. Again, using 1866 or lower RAM could cause less-than-ideal GPU performance.

Quick take: amazing budget/starter cpu, can't wait to see it in more builds!

fast, works really well no issues but it does get hot

Probably the best APU you can get. If you are not a gamer, this CPU will be more than enough with its R7 integrated graphic card.

I got it for $104 before taxes.

great APU. used it while I saved up for my GPU, and considering I mostly only play league, I was getting fairly decent fps (over 100 at highest settings) but found the stock cooler was so loud! (fine if you don't care about it being noisy) Never had any trouble with it, but make sure if you are using it as your only graphics that you get some high speed memory. (as your apu will use your memory as graphics memory)

Great APU. Bought it and used it to play league while I saved up for a GPU and it did way better than I expected. Also I'm not sure if this is super bad or not but since I downloaded NZXT CAM I've been getting notifications every now and then (sometimes when I'm only browsing the web or watching youtube) saying that the cpu temp has exceeded 90C. So yeah I would probably suggest investing in a aftermarket cooler. (unless it is just CAM software being weird and unreliable, in which case ignore this lol)

I bought this CPU originally for a Thermaltake Armor A30 SFF Case as I'd moved my i7 4790K out of the case due to heat issues so I figured this chip would be far coolers not having the grunt of the i7. It turns out I was wrong, not only did it run hotter but it has a much lower thermal margin meaning it downclocks a lot sooner than the 4th gen i7.

I then cut a 120mm hole in the side of the A30 case and fitted a AIO water cooler in push-pull config into the case which bought temps down but left no room for overclocking.

The motherboard also had issues recognising the APU even on the latest BIOS and wouldn't run turbo boost at all.

I finally gave up on the board and the case and got an Asus A88XM-Plus board and a Mid tower gaming case and upgraded the two AIO fans to noctua NF12's for as much performance as possible.

With that setup I was able to overclock the APU to 4.5Ghz safely and it does run well I don't think it's worth it over other options anymore.

It hauls that's for sure :D.
