A wise man once told me that the least you should get for a gaming rig is an i5, so I did. And I might as well get the Skylake while i'm at it. But in all seriousness, it is currently cheaper than last gen's i5 4460 in some places. I don't see why anyone shouldn't get it. Oh, and it runs as well as it should.

Great CPU, wish I had went with the 6500 but amazon was out of stock and everywhere else had it priced higher the the 6600 :/

I know I could have gone last gen but I wanted to be able to upgrade soon, so I might as well get something for a 1151 mobo. It's fine for my purposes as I'm notoverclocking, running 2 GPU's or anything crazy.

The i5-6400 is great little performer, and future upgrade savvy as it hits the recommended specs for a VR ready system! (you'll need to upgrade the gpu to GTX970)

For my gaming needs it runs great, low TDP, low core temperatures, and hasn't given me any issues so far. Not as powerful or as overclockable as it's -K brethren but certainly gets the job done in cool fashion. Bang for buck I give it 4 stars since it's a great little CPU, but loses a star since Intel have been keeping overclockers from unlocking the potential of the chip.

Overclocked to 4.5Ghz without much issue at 1.3 volts. Great value.

Happy with it, on Cpu Z it shows 3.300 MHz on it so i guess it works good.Got nothing to compare it with but its usually under 50% and everything is pretty fast.

Allows me to play CS:GO at 250 fps on highest settings. Can't really find any cons. Overclocking is not really needed.

Great little guy! Fast, easy to install, no problems at all. The stock cooler is nearly silent and does the job. If you want to game and not break bank, buy this cpu.

Planned to run with the 6500 but then stock ran out so I settled for this. Meets my needs and performs very well. Also got mine to clock at 4.5GHz stable.
