I am a retired computer engineer. This little ultra kicks ass and takes names. I am very surprised that it runs this fast. I built an Gigabyte Z77 with i7 3770k processor and this runs circles around it. I do a lot of multi tasking and don't care how many programs I open and work on, this little demon blazes right thru it without a sweat. It arrived looking like brand new, even smelled new. I mostly wait until I have had a unit for a few weeks or months before a review. But, this is so great for the money, I decided to go ahead and review it. If all  mine, can't go wrong. I think I will order 10 more for the family. I am adding from here as I have had it for 2 weeks now and I love this little jewel more all the time.
