Summary: For the price you can't go wrong. Haven't tested 4k video, but I'm told it shouldt have any problem.
Pros: Great little processor! Currently using it for my HTPC and it can take everything I throw at it. The on-board graphics have no issues running movies, SNES/N64 emulation all at 1080p. MadVR (high quality SD upscale) runs at mid-high settings with no issues. All the audio/video can reclock to 23.9xx hz..
Cons: Only issue I had was originally with Kodi the colors seemed washed out playing SD DVD. This is where I read up on external players using MadVR. Eventually I went back to the integrated Kodi player and the color issue was fixed. Determined it was best to leave the Intel HD settings all at "application preference", and I limited color space in Kodi.
Summary: No need to spend more on a more powerful processor for a everyday use computer. I've built nothing but AMD systems since 2001 due to cost, but Intel turned the tables with this processor. This processor replaces a old AMD4850e. Uses 1/2 the power for twice the performance.
Pros: Powerful processor that runs cool, entire system uses 50W at idle. Runs virtually silent. Onboard graphics perfect for HTPC application. Plays nice with Linux Mint 17.1
Cons: Heat sink mounting, but that is common to all LGA1150 processors.
Summary: I almost passed on this little puppy, thinking it might not be up to the job for an HTPC build, boy I was wrong. Works well for an xbmc build, daily computing and some lite non- intense gaming all without a gpu.
