    Perfect for mid range gaming build.

    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)

    With light work with Adobe Illustrator and InDesign, as well as lots of gaming, I couldn't ask for a CPU any more powerful. It does its job just fine.

    When it came to the cpu I decided on the i5-6400 to better fit my budget - AMD has not won me back yet. There was no reason for a 6600k and the differences in the 6500/6400 are so negligible that it wasn't worth the $50 additional cost at the time. I could have gone with an i3 and been fine, but having four logical cores allowed my wife to benefit better from the photo editing software I installed on the computer.

    A very decent starter processor for gaming.

    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.

    While my original plan was to pick up the extremely popular and potent 6500/1060 combo, I bought most of my parts around Black Friday, and because of stock, found a much better deal on the Core i5 6400. While it may not have quite as good of a bang for your buck option as its older sibling, the little brother of the 6500 is still a very capable quad core locked CPU, with solid clock speeds, and no hints of bottlenecking with the likes of the GTX 1060 or RX480.

    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.

    from completed build First windows pc

    very good bang for your buck. cpu itself is very powerful compared to anything I had before and has similar performance toa an i7 3840qm. also, the igpu is surprisingly capable and can handle some light games at 1080p
