This unit is fast any bottle neck will be caused by internet connections that may slow things up a bit. It is fast. The mouse that came with it was crushed in shipping I had read about this happening before.  Confuses me since it all looked packaged nicely.  I would not have used it anyway so it is not an issue. Windows quit after a couple of months had to install new windows 10 to activate.  eighty nine dollar expense should be explained in cost caused be shipping with inactive version of windows.  still happy with computer.
