Actually you have to do it the other way around.
Look at the respective software packages or websites for what you deem to be "good" game. The packaging and/or websites often list the necessary hardware requirements in two or three categories: e.g., minimal, recommended, and best.
You do not want minimal, recommended for certain and as much "best" as you can afford or upgrade to.
And remember that most "specs", both hardware and software, are established in ideal circumstances.
Notebooks tend to be on the low side of meeting software requirements: especially for games.
Games may play but likely to be slow, lag, etc. Plus there will likely be some adverse consequences over time due to heat, keyboard pounding, etc...
