Fastest Computer i have ever bought!!I mean yeah it wasn't brand new but you could barely tell. The only sign of use was they forgot to put back a small metal  part of the back panel  but that's it. It looked and smelled brand new. It even came with a keyboard. The only complaint was that it didn't come with the VGA cable and the VGA is horrible for photos and text but You-Tube is fine. You-Tube shows in 1080P just fine but i was surprised to see this used VGA not DIV or Hdmi.Just how fast?  I hit the power button and in less than a minute it loads up. To turn it off hit the power button and in about a minute it completely turns off.Just how fast? I launch Mozola browser and in seconds it loads. I then got to You-tube ....open up 25videos and play them all at the same time ....Open Chrome browser open 25 youtube videos and play them all at the same time then open 50 VLC player instance and play them all at the same time. Then open as many photos as i can plus open 25 Windows folders plus google earth and the results ......no problems. The CPU never ever goes above 17% Never . I have been unable to get the CPU to go above 20%Memory? the highest use the memory went was 40% and remember that's with 50 YouTube playing at the same time /25Mozola/25Chrome/ 25Windows folders open/ bunches of Photos open/ 50 VLC videos playing at the same time....yet the memory never goes about 40%
