How many GB of RAM are being used if I have a few Chrome tab open while playing games like CSGO, LoL, TF2, etc. And using a voice chat like Skype with an antivirus and Geforce Experience or Raptr? I know I could check it myself, however, my laptop broke few days ago and I want to know real world usage. I know I could google and I did, but the information isn't relevant to my question and not that useful.
