This isn ' t really a support sub , however here is my advice . Personally I use a separate drive for my home partition where all your personal infofiles would be stored . Using a separate partition will give you the same effect , but be sure to keep a back up of everything anyway . Xubuntu and Ubuntu or Kubuntu , Lubuntu , etc are all basically the same under the hood , but the difference is in the Desktop environment and what programs will be installed by default . I haven ' t used WINE in quite some time , but the last time I did Office Worked without issue with it . However , LibreOffice will be installed by default and I would say give it a go before trying to use WINE . CSGO works quite well , and yes you would just install steam and go from there . That said be sure to check the system requirements as the Linux ones can be a bit different from Windows . You will also likely need to install the proprietary drivers for your graphics card Xubuntu has a tool built in for that , so it should be pretty painless .
