First off, let me say that before I even got started I opened the computer to see how many RAM slots there were. There were 4 and 2 were empty. I had 2 DDR3 8gig sticks from a broken computer that I then added to this machine, so unfortunately I can't speak for the performance straight out of the box. Hence the "*" in the title and the 4 star rating. After starting this computer up, I am really impressed! It is really fast and has no trouble streaming from my Xbox one in the bedroom. I played Red Dead Redemption 2 for hours without any problems.
