You should definitely give it a shot! Due to proton, you should be able to play most, if not all, of the games you play om windows (unless they have obnoxious anticheats). A good resource for checking game compatibility on linux is ProtonDB. In terms of performance, there will almost certainly be a slight impact, but in my experience (with an admitingly far more powerful gpu) it really is minimal. And if it really doesn't work out, you can always go back to windows.
