AMD A10-5800K - A-Series APU Trinity Quad-Core 3.8 GHz Socket FM2 100W AMD Radeon HD 7660D Desktop APU (CPU + GPU) with DirectX 11 Graphic - AD580KWOHJBOX

Pros: This chip is fantastic. It's very close in speed to the i5 sandy bridge line but for a lot less money. The graphical power is pretty nice too and runs stable at 866MHz (800 standard) in every build I've tried it in. That results in approx a 6.4 rating in WEI, give or take a bit depending on the RAM speed. I've seen it get up to a 6.8 with dual channel native 1866 RAM on a good board.

Most A10s run at 4.0GHz without upping the voltage but a couple hops up results in stable operation at 4.2GHz. Despite being 100W TDP, this chip really doesn't get hot. At stock speeds, running Prime 95, it got up to 104 Fahrenheit. At 4.2GHz with 866Mhz GPU core and the voltage around 1.420, it only reached 117 degrees with stock cooling. On my new Xigmatek enormous cooler + arctic silver, it didn't cross 108 no matter what I did.

Cons: The fan is TERRIBLE. I've ordered two A10s and one A6 and all three had insanely loud fans. The heatsink isn't exactly structured for quiet airflow either. My last A10 had a fan that was damaged and sounded like a truck idling and I ended up having to replace the entire heatsink and fan because no 70mm fan was quiet enough blowing across their awful heatsink.

Overall Review: You almost have to assume you'll need a different cooling solution than the stock one which really adds to the cost.

Pros: supposed to be good

Cons: mine was defective

Overall Review: called AMD and they said they had a bad batch but they should of all been returned. said mine was doing what the bad batch did.
